Asking because my rear diff is from a junkyard and has that written on the axle tubes and I would like to know of its different from a 2000 silverado. My spider gears are ate up and I'm looking for different gears and don't want to buy the wrong ones.

 

Thats a 8.5" 10 bolt. where a 2000 silverado is a 8.625" 10 bolt.. Spiders should work if thats all you need out of it..

 

but then again.. it might not... could have 28 spline axles vs 30 spline axles in the 2000..

 

That's why is asked cuz I figured it was an 8.5 vs 8.6. Good thing I asked before ordering gears and what not. Thanks man.
