The splines Bob is talking about are in the Differential, not the
transmission. The splines on the long fixed shaft sticking out of the
transmission engage these splines on the inside of the differential pinion
shaft. If you're looking from the end that mates with the tranny, the
bottom leg of the "L" shape you're looking for will be farthest away from
you as you peer down the inside of the pinion shaft. If you don't see the
"L" shape, and the splines appear square and a uniform thickness down their
entire length then you've got a good shaft and you're in business.

Subject: <VV> question about 1965 4 speed differential
On page 129 of the Corvair Basics book, it says "In addition, the splines
internal to the pinion shaft tend to wear on a MT differential. These
should be checked visually using a strong light and by looking inside the
pinion shaft. The splines should be perfectly square, if they are "L"
shaped or mostly worn down, the pinion shaft should be replaced."
I've got a 1965 4 speed, and I'm having a hard time figuring out how to do
this check. How does one go about looking inside the pinion shaft without
taking the differential apart? I have pulled the input shaft out, and using
a flashlight I can barely see the teeth that it engages with all the way
over in the transmission, but I don't think this is what I'm looking for.
Any help appreciated!
