Yoke interchangeability

[Wildbill0088]

Alright so the drive yoke on my blazer's rear diff is shot so I was wondering if one off an 80s 10 bolt would fit since I have quite a few of them hanging about.

is it a 8.5 rear end from the s10?

They are both half ton 4X4s my 92 K Blazer and the 86 K10 parts junker I plan on yanking the yoke out of if it is compatible

as long as its a 30 spline it will fit from what I have found for the 8.5 rear,It is the most common one in chevy/gmc 4x4 1/2 tons

It shouldnt matter if it is 30 spline or the 87 and older 28 spline axle shafts. The yokes will swap, not sure if the cup size will be the same given the number of u-joint/driveshaft combos.

it will bolt on to the pinion, may not be the right ujoint size

the 86 should be a 1330 joint, the 92 may be the saginaw joint
