ok, last week i completely blew up my rear diff in my 10 bolt. it has the 8 1/2 ring gear and 28 splines. i have been looking for a rear diff at junk yards but i couldnt find any good ones. i dont want to spend any money really because i plan on dropping these axles out as soon as i find the 1 tons i want. but my question is, will the diff out of a 75/76 monte carlo work? my buddy has one down the street and i just have to go rip it out. no cost. does anyone know if it is the 8 1/2 ring gear with 28 splines?
