Gas pedal linkage/cable?

will be going from a /6 to 392 hemi, 66 Dart. Not much room for anything! The current gas linkage rotates instead of push-pull. Is there a stock cable/pedal assembly I can look for or should I try to find an aftermarket setup?
If your not doing any kickdown to a tranny there are several to choose from...Lokar makes a decent throttle cable but do not, I repeat do not use their kickdown cable....you can also go to mancini racing and look at their several different throttle cable setups they have and pick one that will work with you intake manifold..
