1971 colorado state patrol 2 door e85 fury 1

The D69 Special Order Rear Axle is interesting, don't know if I have seen that before. They also ordered the D91 sure grip, which was very rare in a Police Car. Most agencies didn't want to spend the money on one. Is F01 on there? There is a crease right over it and I can't see it. That would be the dual exhaust police engine package (BTW, the car is coded for N41 dual exhaust). This would be the 1st time I've seen that on a 71.
The rear leafs would be the "Hemi" suspension, with 6 leafs on one side, 5 1/2 on the other. It was the heaviest duty Chrysler made in a passenger car. They wouldn't be "wider", just have the extra leafs.
There is always a "never say never" mantra with Mopars. If you bought enough cars, Chrysler would build whatever you wanted.
Roger Mauro was the big Chrysler/Plymouth dealer back in the day in Denver.

The disc pads on pursuit class police cruisers were riveted, not bonded, they were supposed to hold up better in the extreme heat of police service. Rear brakes were usually 11" x 3" shoes. In '71 they were asbestos. Wheel cylinders and calipers are standard production items. Most police cruisers have police specific torsion bars and rear springs. As I recall, the rear springs were the same width with extra leaves and sturdier rear brackets. Your cruiser still has factory rear drums and the factory front disc rotors. Note Pentastar on the rear drum and 2 piece construction on the front rotor.

Great info, thanks guys.

I will get some pics of stuff next time I am by her. I saw a button on the lower left side by the column, must be the trunk button.

Never heard of a n81 throttle...

 

[Davea Lux]

Pretty sure N81 is a throttle solenoid that was usually activated by the light bar. This bumped the engine rpms up so that the battery would not go dead at low idle. Cruisers sometimes sat for hours with the light bar and flashers going and the alternator could not keep up at low engine rpms. If you have a AVS carb on this car, the solenoid will be on the passenger side of the carb.

[Ross Wooldridge]

The throttle solenoid also helped in cooling etc - turned the fan a bit faster to pull more air through the radiator during prolonged idling/sitting, and allowed the AC to function better in the same conditions too.

my 71 T code 440 Fury Custom Suburban (PM45T) has a dual snorkel which it came with from new.
heres the bigger 71 engine choices, you can see the dual snorkel was standard on the T

Is the a thread on this somewhere Dave? I searched and couldn’t find anything.

Thats a quote from this thread ... didn't the guy I quoted post a link?

Very cool police car you have there! I've been doing a lot of research lately on '71 Police cars myself

For those that are wondering, a lot of questions can be answered about the cars in the fleet buyers guide.
In 1971 the police trim (PK vin) was only available on the 4dr sedan (PK41) or wagon (PK45) body style. Any other civilian body style an agency wanted (PE21 2dr coupe in this case) would have had to use the A38 package to get all the police options normally associated with a PK vin.

https://www.hamtramck-historical.com/images/dealerships/FleetBook/1971/71_4_Fury0001.jpg

With that being said Plymouth was weird about restricting the U-code 370hp Super Commando 440 to only PK41 vin (police 4dr sedan trim) or PP23 vin(also known as the Sport Fury GT) in 1971. The PK45 wagon had the T-code 440 as top option (as far as I can tell there was never a '69-'73 wagon with an L/U code Super Commando 440).

https://www.hamtramck-historical.com/images/dealerships/FleetBook/1971/71_Fleet_Plymouth0024.jpg

This limited the top engine available in all the other trim lines such as the PE21 to the T-code 440.

https://www.hamtramck-historical.com/images/dealerships/FleetBook/1971/71_Fleet_Plymouth0016.jpg

Certainly any agency that wanted a 2dr wanted the cheapest car available and certainly weren't gonna spend a premium ordering a GT with the A38 package to get the U-code 440. They settled for the lesser T-code 440.

That is not to say if some agencies wanted the U-code engine they could possibly have pulled a few strings especially if the order was large enough. But as far as standard ordering procedure this is it.

As far as '71 T-code police cars go, I'm under the impression that they all had dual snorkel air cleaners & dual exhaust system with log manifolds similar to what was used for the '69 Pursuit Special 360hp 440 engine.

 

[67valiant 100]

I believe D69 special order axle is in regards to them not using the ISO rubber leaf spring perches. Every other civilian chassis C-body that year would have had the quite ride ISO perches hence the special order axle. The other possibility could be the use of 3.23 gears behind a T-code 440. The standard gearing for T-code 440 was 2.76 gears in Furys. The 3.23 was optional but not commonly done. I'd imagine they would have just used the D53 code for 3.23 gears if that was the case. @robio would have to crawl underneath and verify what gear ratio it is.

The non-ISO C-body 8 3/4 housing with whatever gearing plus a sure-grip unit is not a typical sub-assembly unit for 1971. I am unable to find the 678 part # axle subassembly in the parts book.

Assembly 768 is just that...a group of individual parts put together to make one larger piece installed as a unit. Therefore, assemblies not be listed in the parts book.
Individual parts of the assembly will be listed; but not the assembly.

 

[67valiant 100]

Axle sub-assemblies are listed in the book. However upon closer analyst the 8 3/4s are listed housings separate from carrier & gear (for obvious interchangeability reasons). All other axles are complete housing+diff assemblies. (section 3-03-3, pg 3-3)

[67valiant 100]

Ideally would like to find a list such as below for all '71 models. I dont know where one would aquire such a list though..

 

[robio]

Not a progress update quite yet, but there has been some interesting discussion around here with some of the locals about this car.

The Roger Mauro dealership tag started some good stuff. That family was into far more than just a dodge dealership. One old timer pointed out that the mauro name is huge in Colorado racing history. I checked and there is lots listed online about them and their accomplishments.

Nothing directly related to this car, but might shine a light on why so many uncommon options and how it came to be. It is clear it is not the garden variety 71 police car. No direct proof, but maybe there were some knowledgeable people who understood how to get the maximum performance from the pool of parts available, and also knew how to get what they wanted through the ordering process. Makes sense to me.

I am working on trying to meet some relatives, and also some retired tires troopers.

More pics in a few days.

Very cool cop car, one of the more unique ones out there

N81 is a manual high idle control - it will be a black t shaped handle to the right of the steering columns on the bottom of the dash frame. Cable connects to the throttle linkage. That is most likely in the fuel section of the parts book. Keeps the battery charged, ac and lights running and prevents over heating.
Please look in the PARTS BOOKS which seem to be a mystery on here.
But don't forget the car needs a woman's name or you can't talk about it....lol

The solenoid controlled fast idle is wives tale - in the later years ac cars came with a solenoid to increase the idle speed a little bit. Show me in the parts book.

D69 special order axle the elimination of the ISO rubber leaf spring perches.

There should be about 125 extra welds on the car with some reinforcement plates in various locations.

that section refers to the carrier, “pig”, “pumpkin” unit. It’s one part of the total assembly. The axle assembly listed on the Broadcast sheet comes with shafts and brakes.

thanks to @Big_John we have a partial answer. (This is from the file you gave me at Carlisle.)

Shown is a spreadsheet grid of available axle assembly combinations for 71 C bodies. Column headers show applications for wagon, non wagon, P,D,C applications; police, taxi and trailer towing sub broken down by engine combinations.
So this tells you what the various assemblies the factory planned for production. What it does not tell us is the assembly number.

With some decent research of broadcast sheets, one could reverse engineer the coding and complete the grid.

On point, this shows us what assemblies the factory accounted for in 71 C body police cars with a 440. It just doesn’t give us the actual assembly number.

This is one more reason to find and save as much factory info as possible. Every broadcast sheet helps fill in this grid. Every file and every piece of paper helps answer a question at some point.

Interesting background info but let’s not let anecdotal stories replace solid research.

I don’t think we have determined that some of these items are uncommon. Our pool of comparable cars and applications is pretty small.

This line of thinking also asks us to consider that guys familiar with racing components and applications believed they were more competent that the factory engineers to pull together specific parts for the bin to complete an axle assembly. It would be easier for a dealer to replace parts one the car was received.

Let’s not jump to conclusions before we’ve exhausted logic and facts. Speculation leads to errors.

Yes. The homemade Irish cream was tasty but this is useful!
