Need some help finding "clutch set" for my sure grip rebuild

I am having a little difficulty locating a "clutch set" for my sure grip rebuild.

I was looking at this:

Yukon Gear & Axle Differential Clutch Sets YPKC8.25-PC-T/L

https://www.summitracing.com/parts/yga-16147/overview/

but a feedback report says that it does not work with the 96' an older 27 spline 8 1/4" axles

any help pointing me in the right direction would be great, thanks
