throttle linkage

I have just installed a 360 crate engine in my 65 Dart. I retained my original gas pedal (discarding linkage) and modified a later "floater" type pedal so I could use a stock Mopar throttle cable. The late pedal assembly is mounted to the firewall, and the cable is routed like later model cars. The late assembly's plastic pedal is removed and the remaining round metal modified as necessary. The original pedal now pushes on the later model pedal assy. Works well (so far) and looks stock. Hope this helps.
