The main difference is that the later 307 Olds Q-jets were computer controlled and do NOT use the same linkage. The hole for the pump arm is much larger so they will not work on the earlier q-jets without stripping all the parts off that end of the shaft and installing the earlier bracket.
I'm pretty sure that distance from center for the geometry is about the same or at least close enough that it works fine. I've used many early units originally set up for TH350 kick down cables for 200-4R's and 700/4L60's and never had a problem fine tuning the shift points with the adjustable TV cables.......Cliff
