8.5" 10 bolt spline count
What year did the 8.5" 10 bolt switch from 28 spline axles to 30 spline? I know it was sometime in the 80's, but no idea what year. I need to know what my '85 came with.....it's about time for a locker.

An '85 would have come with 28-spline axles. The 30's didn't show up until '88 or '89.

Re: 8.5" 10 bolt spline count
my 86 had 28 spline, I upgraded to the 30 spline when I rebuilt it.

Re: 8.5" 10 bolt spline count
I'm also wondering this. I have 3.73 gears from my 2001 silverado that i want to put into my 83 sierra. What would i have to change to make it work? Theyre both 10 bolt.
