What is an 87 1/2?
Seriously Tex? I have a 90 and a 1/4 figure it out
Only differences with the 87's were the axle splines.
Some 88's came with 24's. When the swap over changes happened at the factory the bulk of 250s in late 87 early 88 got 26 splines and then random one's got a 24 spline till they were gone.
