I was thinking the same thing, the 86 uses a needle bearing opposite the clutch, the newer use ball bearings, hmm maybe the 87 uses the needle to, I'll have to look at that, or you may be able to use the shaft from a newer unit and use the neddle bearing, gotta think the cases weren't changed drastically.

Interesting.  I have been searching for this hub for a year now.  I wonder how tough it would be to get that shaft out.....

BDI:
You will have to split the cases.Not a big deal really unless you don't know how or have the tools to do it.

Looking at the fiche, it looks like you could use the shaft from an 87, and of course you'd have to use all the clutch compnoents as well. I don't think you could use the newer shaft from say 89 and up, it doesn't have the snap ring groove and probably isn't long enough. Maybe the 87 clutch is the same as the newer clutches, didn't look at that, if thats the case, you could replace the shaft and get a cluth setup off ebay cheap. I had a 86 hub, but one of the spring towers was broke off, I might be able to weld it back on. Whats wrong with yours?

BDI:
I have fixed spring towers before by drilling the tower hole all the way through the hub then counter sinking the back side of the hub for a flat head phillips screw then I just screwed the tower back on from the back side with red locktite. Not exactly the way I like doing things but it worked.

don46:
Great thought, they really only hold the spring in place.
