Just jumping on the cbarge band wagon...
I did the bypass in my 65 Sport Fury. Took no longer than 15 not including crimping. While I was there (the best train of thought when you're working on these cars), I cleaned and inspected all my wiring and connections, replaced old relays and checked anything that looked old, dirty or broken.
I'm a veteran Volunteer Firefighter with a Department on Long Island that covers the Robert Moses Bridges and Beach areas...including Ocean Parkway. I say this because they are hot spots for these old cars to hang out and many shows take place over the summer months at Captree Boat Basin and Oak Beach (Inn) parking lot. If I had a dollar for every classic car fire I've been to on the route to these locations...I'd be well retired. Everything from modern to vintage has burned on the bridges and in the parking lots. All I can say is if you own a classic and do NOT ride with at least 1 $20 Kiddie FE mounted in your car ... You are completely ******* insane.
As far as safety...the first thing on your mind should be to address any potential fire hazzards these cars rolled out of the factory with. One is the Bulk Head Ammeter bypass...another is the instrument voltage regulator upgrade...another is changing over your head lights to relay style and getting all that power out of and away from that bulkhead connector. It's the death of many Mopars and old cars in general. I've seen it.
Anyhow...I'm off the soap box ... Have a safe weekend!!
Cbarge is a great help and I'm looking forward to the write-up so I know more of these cars will live a longer life.
