Locate cable accelerator pedal in relation to single barrel linkage

OK, took another look and it's clear from the OP's pic of the engine compartment that he has a 64 or later. So yeah, it will have the dimples. Problem these days would be finding an original 64-66 V8 pedal setup. If not, the later swing pedal could be made to work.

As for the throttle and kickdown linkage, I used a factory two barrel setup, slightly modified to put the cable end at the right place for a four barrel, lengthened the kickdown flat rod by welding two halves together, and cut and welded the lower rod to the original 63 rod.

So:

As you can see, the throttle cable comes out of the firewall where the original throttle rod did. Most observers at a car show won't realize that none of this is original 63 throttle/kickdown stuff.
