I'm in the process of dropping the ST-300 in my 67 Skylark for a rebuild. In the process I've combed over the draintrain to replace worn components. The existing front U joint was heavily worn and appears to have resulted in a pretty well bombed yoke. I see a bunch available online, mostly for BOP TH350, which as I understand, should be interchangeable. However, when I measure the length of the yoke I pulled from the car, I get 5". What I have found available on the net is 5.4" - 5.5". Perhaps I am meauring incorrectly? Center of cap to shaft tube end. Better yet, can anybody recommend a good replacement that will for sure fit?
