Hey everyone! I just got a 1990 GMC light 3/4 ton 4wd given to me. Bad engine and body. My question is if the front and rear diffs are interchangeable with my 1995 GMC 1/2 ton 4wd. The 3/4 ton has the 14 bolt rear and possibly? heavier front diff. Both trucks are 6 bolt axles. I know the rear diff will fit but I am wondering about the front. It does look the same. Any comments would be appreciated.
