Speedy is correct about Bowtie Overdrive's TV cable setup. I looked at several, and theirs is the best out there. Instead of trying to attach something to one carb stud like most others, it's built onto a full carburetor plate. There's no way it's going to move. I did have to make an adaptor for the throttle cable though.

They have some good technical info on the site also.
