Looks good! Those are some big chargers for a 4 banger. Have you had it on a dyno?
Ain't a 60......its a 1/2 ton GM axle of some kind........
BUT with mud...you dont have a ton of shock load like you do in rocks and such and its all in a stright line....there are some guys out there that have Dana 30's that run cut 44" Boggers......Im sure is a weight thing.....run good axles (Cromoly) and joints (CTM's)....might work just fine.....
FASS looks good! Will look better with some mud on it! :Cheer:
