How many using an A500 overdrive ?
I ordered a slip yoke for my A500, but I don’t know where the paperwork is right now, so I can’t give you a part number. I am measuring 1.680 on the outside diameter of the yoke. Here is a picture inside the end of the yoke, but I see full spines on the output of the transmission, no specific double wide one to fit that wide slot. Looks like it will go on in any position.
and yes, it does fit, I have driven the car, albeit only a few miles before the trans I paid someone to build for me crapped out, but not before they went out of business, hence me teaching myself how to do it correctly
