1963 Dart swap to cable throttle?

I really like this setup and I'm planning to replicate it in my 63 Valiant. I'm curious about the V8 pedal and what the backside looks like. How does the spoon ride on the pedal and what differentiates it from the Slant 6 pedal. I have 2 early pedals, one in my car (rotating rod style) the other i picked up with some parts and I don't know if it's the one I need. Do you know the part number of your pedal or have a pic of the backside so I know what to look for? Thanks!

Here's an old ad on FABO that shows the front and back side of the V8 pedal. One is missing the nylon rub pad, other has it. For Sale: Early A-Body V8 Gas Pedal Valiant Dart Barracuda

And it looks like Detroit Muscle Technologies offers a new reproduction (without the nylon pad?). Mopar A Body 63-66 Accelerator Gas Pedal (for V8 cars)

To use the V8 pedal, you would also need the 64-66 V8 firewall throttle bracket so you could cut the spoon off it. Or maybe adapt something similar, but I have no idea right off hand what might work.
