quick question

Hey guys I am a little unfamiliar with rear end terminology so please forgive me. When you hear the terms (7.5", 8.5", 9") rear ends, does this reffer to the diameter of the ring gear?? If it does and I have a 10 bolt chevy rear end with a 7.5" ring gear, can I take it out to swap in an 8.5" ring setup or do I need to replace the entire unit?? Thanks!!

yes the size of the rear is determined by the diameter of the ring gear.

and no you cant put a 8.5" gear in a 7.5" case. its like trying to put a 4" ball thru a 3" hole, cant be done.
