changing a rear end

Yeah...I'd say swapping rearends will take you 2-3 hours. Fairly simple. Just don't forget to disconnect that soft (rubber hose) brake line that goes to the hard lines on the rearend. wouldn't want to drop the rear thinking it's ready to fall out...& have that line hold you up...or worse...brake or kink the line or fittings. as for the gears...I had mine done by a speed shop. That's about the only thing I've paid to have done.
