Ah, that's how it goes.
Clair, you are right, you cannot reverse the tb. That was the first thing I thought of. It would screw with the iac.

If no one makes a kit, then feets wants to build a bracket that holds both the original cable and kickdown on one bar, and a bell crank to move a second rod or cable to actuate the tb arm.

I was just hoping someone had already fixed this problem.
