Robio, you've definitely picked up an unusual car. Its configuration raises a number of questions. Not having seen the entire VIN, and just looking at the photos you provided including the fender tags, I see the following:
1. E85 = 440 motor
2. A38 = police pkg.
3. F36 & F37 = possible right & left 5" spotlights
(F33 & F35 were 6" spots)
4. F38 = reinforced roof for light bar
5. F58 = right rear reinforced weld
6. Y39 = special order
7. EW1 = white exterior color
8. V01 = monotone paint
9. Correct police aux. map light
10. Correct interior trim
Things that are unclear:
1. Whether speedometer is certified (although quite blurry, it appears to exceed 120 mph).
2. Whether the floor is carpeted or industrial rubber.
3. Presence of mounting holes on driver's side roof for red light, but unable to determine if matching holes are on passenger side. You claim two red lights were removed.
4. You state you observed "serious exhaust hangars and brackets." This could be consistent with the F58 "reinforced RR weld."
Things that are odd, unusual or inconsistent with evidence or text:
1. Presence of cb radio. (Meaningless.)
2. "440" engine call-outs on bottom corner of front fender. May or may not be factory installed. Photo of CHP Fury from 1973 map does not have it. Photo of Rhode Island squad by other subscriber does.
3. You claim the 1973 Colorado road map which depicts the CHP squad with the trooper standing next to it "sealed the deal" that it was identical to yours. Unless I'm missing something, that photo clearly shows a 4-door sedan, not a 2-door like yours. On the other hand, the photo of the Rhode Island squad is obviously identical to yours (thus "sealing the deal" for me!).
Lastly, being from Wyoming, and quite familiar with Colorado State Patrol livery, I know that vintage CHP units were white with spotlights on both sides.
Taking all of the above into consideration, notwithstanding some of the inconsistent items, I'd have to say you've stumbled onto a bona fide CHP unit. Perhaps the 2-door cars were used by various state agencies for special purposes, such as pursuit or senior management (and not necessarily prisoner transport or confinement). Well done, and good luck!
