In my quest to fix this abomination of slapped parts together on my buddy's car....He he has a 58 Fury with a 440/727 combo. I already have the Bouchillon kickdown kit on the list of parts to order. His accelerator linkage is a solid piece of steel welded to a bolt and it connects to a bell crank. Honestly, he isn't looking for retro, he is looking for driveability so if I can stuff a cable in there it would be better for everyone and get rid of the bellcrank...thing is....I am not up to par with the 1958 model year. I know originally this car had a 318. The Bouchillon kit provides a clean look in the engine bay and I wanna make it perform better by adding a throttle cable all on one bracket....thing is...Bouchillon offers a square style and a round style...and I dunno which one it is. Anyone have knowledge on a 58 model year? http://www.bpeusa.com/BPEcables.asp

No cable operated throttle in those years. All rod-linkage.
Don't think they had square drills back then so I would choose the round one...

the rod that actuated the throttle pushed rather than pulled.

Mechanical linkage only, throttle and kick down, on all pre 1962 Mopars Cable shifter until 1965 on the automatic cars

Yeah I am going to back off of it and make his bell crank / rod do the work. I thought it had the hammer style like my 69 but it doesn't...just going to install the BPE kickdown kit.

Thanks fellas

I had a 1957 Dodge that I put a 440 in. If memory serves, I used a complete 1965 Fury "C" body throttle linkage setup (cable, pedal, bellcrank and wheel).

I put a pedal and cable in my 57 Fury. One from an early seventies B body should work. I have a 440 with a Performer RPM and it works great. All I had to do was drill a few small hole to attach the pedal assembly and make another hole for the cable.

My buddy used a Lokar cable in his 1958 Savoy when the twin carbed 440 went in.
The pivot for the gas pedal is actually below the floorboard. I do know he had to make a bracket to hold the cable away from the firewall as it came up to the carbs.
