I've produced a few Quadrajet TV arm conversion kits for the guys swapping in a 200-4r or 700r4 transmission. The kit works for 68-74 Olds and 68-76 Buick Quadrajets, which came without the lower TV cable arm.

Used to be one would have to swap on an incorrect throttle arm, swap out the entire primary shaft, or switch to a different carb entirely to be able to run a Throttle Valved overdrive trans like 200-4r or 700r4.

This conversion arm installs behind the stock, correct throttle arm. Keep the original form fit and function of the stock throttle arm.

Looks like a good product that fills a need GLWS
