Anybody know if COAA-6550-A is a good number for a '64 Truck with 3 on the tree. I would think it's fir a car, have been burned buying parts before. Seems nothing is simple anymore for some reason.

I want to lay in this part on hand, it is listed as 10.5" but I see some listings as "fine spline" and that gets my ears itching, my drawer full of unusable parts is plenty full already. I see C3TZ-7550-? as the truck version?

Thanks in advance. Ted

You may not like this advice, but to make sure you get the right parts is to pull the trans and clutch and see what you got and order accordingly.
