holley 4010 kickdown?

I understand you are replacing the stock cables. If your pedal assy. (not cable, pedal assy.) wasn't held on by 2 nuts it must be different than mine.

What kind of car do you have?
oh sorry. didn't understand what you were saying. the pedal assembly is held on by 2 bolts that go into the floor.
And even If I would have removed the pedal assembly, the entire throttle cable would not have fit through the "grommet" on the firewall

and this is all on my '73 satellite. I know its not an A-body. but I knew that there would be very knowledgeable people like yourself that could help me with it..
