Does anyone know the rear differential spline count on this pickups?
I'm looking at putting in a Lock-Rite from powertrax

Drop In Lockers from PowerTrax

They have a "new" design out for the 28 spline, thats supposedly better at not "chunking" on turns.
Anyone have experience with these and would like to chime in?

I read this thread, and it looks like this guy was having some issues with the unit.

All the other threads, look pretty old, and if any one whose been running these for awhile could give me an update that'd be fantastic!

Let me know, thanks!

The rest were all 26 spline until 1996 i believe, will need to double check that though
