A couple of notes, I had an older 3550 in the car. The internet said it had a 31 spline output shaft, but I had a 28 spline. The new 31 spline yoke was a little but longer than the old one, so I have about 3/4" of travel into the transmission. Running it through the range of motion, seems like it's plenty for my setup.

I also had to change to a 26 spline clutch (from 10 spline). My clutch cable was always super tight before with a spec clutch, now it's pretty loose. My firewall adjuster has enough adjustment to compensate.

Getting parts has been somewhat of a PITA with supply chain issues.
