I am looking for a rear differential for a 87 full size blazer 4WD. The blazer has a 10 bolt rear, 8.5" ring gear, 28 spline axles, and has to be a 3 series carrier. Preferrably a posi or locker unit, but doesnt really matter. I need one CHEAP! I have to get this blazer im working on out of my garage and im having trouble finding a match. let me know, i need one ASAP. Thanks

I have the same size with a 30 spline... im not positive.. but i think a 28, 29, or 30 spline is compatable.. im probably wrong so ask around.. but I have a 8.5 III series carrier for a 10 bolt coming off of a 01 silverado.. its not a locker.. its just a stocker.. let me know if you think it'll fit and what you would want to give me for it... its in good condition.. didnt do anything stupid with it.. just switched for a posi and 410's

 

Thanks for the reply. Your carrier would fit just fine, but it has too many splines (if it is in fact a 30 spline carrier) for the axles i have (28 splines) and would not work. Let me know if it turns up to be a 28 spline. I am also open for some 30 spline axles, I'll have to check the length on the blazer because i dont know if they are a different length than a regular pickup.
