Big block 727 kickdown linkage rod

Kim,
The rods in your 4th picture look like the type I need as they have the pin (or whatever it is called) on each end that uses a retainer type clip that snaps on to the rod. I measured my bellcrank and trans. lever holes today. They are the same size. I guess they would be considered 1/4" but a 17/64 drill bit will go through them as well.
