A 10 bolt is not a 10 bolt when you're talking about the S-10 version. The fullsize half ton version is an 8.5" ring gear, C-clip axle with either 28 or 30 spline axles depending on vintage. The S-10 version has 10 cover bolts and that's where the similarity ends. The ring gear is only 7.625" and nothing swaps between the two diff's.Rosie said:hi there, i have just picked up a ten bolt rear end out of a full size blazer. i have a S-10 with a ten bolt rear end. the gear ratios are the same.
are the gears interchangable? can i just swap parts between the 2 rear ends?
