The 8 1/4 thread

OK - so from what I understand is a Dana 35 locker will work in a 8.25?

Do you use the entire center carrier or only the locker when moving it to the 8.25? explain please

What is the year cut off for a Dana 35 to go from 27 spline to 30 spline?
--- I Believe for an 8.25 it is 1996 or newer?

I have a 73 8.25 with 3:21's. I have found a Dana 35 from a 1998 Cherokee with brakes, 373's and locker - Can I transfer everything into the 8.25, including the brakes
