my buddy had one that was bodied on 19's and i beams, the booster is all that stopped 20's from working and it untucked them no prob with bags. it had a cantilever up front with the bags mounted up front next to the radiator. only real problem was that to pull the motor he had to cut out a bunch of the front suspention or else pull the cab.
