Parts required to replace axle/pinion Yoke?

[tom h]

If I was to replace the yoke on the axle (for U-joint & drive shaft upgrade), what other parts are required to assure a reliable, quality install?

I believe I should plan on replacing the "crush washer" item 10 and probably "seal" item 8 (?).

Comments & feedback?

Also, how many yoke splines are used on the 1987 stock, positraction axle?

TIA.

Well , I found #10 is just an ordinary large flat washer and not the "crush" sleeve/washer.

The stock gn and t-type axles have 28 splines. i would also buy the crush collar and pinnion seal.
