I have a 1961 T-10 Transmission. The output shaft where the yolk attaches has 23 teeth. Normal is 16 I'm told. I have called Richmond Gear (they own the T10 patent now) and half a dozen Corvette shops around the country. My local driveline shop can't find anything. No one has ever heard of a spline like this. The ****** is pristine. Never rebuilt, or molested. I can't find the guy I bought it from. Before I do something drastic, is this a rare trans from GM? Anybody have a yolk? Any help is appreciated. This yolk is literally the last piece of a five year project.
Full size Buicks and Oldsmobiles used this one with a bolt-on yoke. You'll need to change the main shaft to use another yoke.
