Older stock Dana 60 35 spline inner axles (particularly pre-1980) neck down from 1.5” at the splines to 1.3" in the middle of the shaft.
Later Spicer inner axles (1980+) are 1.500” at the splines. 1.562" at the seal surface, and taper up to 1.625” at the largest diameter. The part numbers are the same for the whole run ('77-'91), but around '80, they changed to the bigger shafts. (They were gradually phased in over a few years)
In order to upgrade an older "neck down" shaft to the larger models, one need only order the standard stock part number or application, and, assuming your supplier doesn't have any really old stock, you should get the larger shafts. This is true for all 3 - Chevy, Dodge, and Ford.

I know the later 10 bolt shafts were 1 5/16"s thats just over 1.25. So yeah neckdown shafts are about the same size. I don't want to put my High Pinion 60 back together till I get non neckdown shafts, aftermarket or OEM.

I have pulled down three different 1979 K-30's and all of them had the fat inner axles . Always check to be absolutely sure .
