Off the top of your heads, what is the diameter of the 28 spline axle shafts? Not the axle tubes, but the axle shafts. Can't seem to find an answer on the interwebs or anywhere else. Thanks.

What part of the shaft?

camaromike222

Oh, forgot about that. I suppose both long and short bearing part. If possible.

You talking about a 10 bolt or a 9 bolt?

camaromike222

Darn, I keep forgetting the important info. Sorry about that. The 10 bolt. The reason I ask is because I'm curious if the axles work with a GM 8.5 10 bolt carrier or LSD with the 28 splines. I would imagine they would be different, but I would love to know. 28 spline 8.5 shafts are 1.285' I think. I was thinking about doing a "pumpkin" swap. The 8.5 housing for the 7.5 and keep the factory tubes. Kind of like the 8.8 diff someone wrote a thread about. I'm crazy, I know, but very curious. The TA mount should be easy enough to fabricate.

7.5 and 8.5 28 spline axles are the same size at the splines and at the bearing. The c clip buttons are not the same.

camaromike222

Ahh ok. I suppose this is good news. Perhaps the C-Clip problem can be remedied. Thank you very much.

The 7.5 uses a smaller c clip than the 8.5. Don't know how to get around that.

i have four 28 spline axles.1991 and 2000.do you still need measurements?
