V8 throttle pedal for my A body

Through 66, slant sixes had a rod, not a cable.

If the OP is working on a 65 Barracuda, he will need the V8 accelerator pedal, V8 throttle cable firewall bracket, and an A body V8 cable, preferably a four barrel cable. Repop 340 cable will work just fine.

Edit, if you don't care about looking original, a later A body swing pedal setup can be made to work with just a bit of trimming.
