Title: Front locker
Post by: Java110 on June 06, 2002, 03:43:00 pm: I found a locker that I would like to put in the front of my truck, but i'm not sure if it will fit. It says it will fit into a 8.2" or an 8.5" 10 bolt. I know the rear is a 8.5" so I would assume the same for the front. But is it 10 bolt? Also it says for 28 spine axles. Anyone know what I have in the front? The truck is an 85 silverado 1/2 ton.
thanx

The 30 spline axleshafts came in the 88-91 Blazers and Suburbans and can be swapped into earlier axles along with a 30 spline carrier for a tad more strength.
