The 8 1/4 thread

here is the guy i got mine from gofastgearhead on eBay and he has a couple 8.25 carriers but one just like mine is a 29 spline and the other is a 27 spline which mine was.

i like it because it was decent priced and the gear set came with it and i have done the guesswork and experimenting as far as the bearings go.
