I took the drive-shaft off, but my buddies Sal and Mario did the entire new Ring & Pinion and True-trac install. I was happy with my old 3:42 gears but unfortunately they don't make a True-trac LSD that fits my 1977 12 bolt with that ratio, so we went 3:73. It's great, different feel with both wheels driving the truck. Yes its a GMC with leaf spring rear.
