buddy o mine ran f100's up front and f150s out back with a drop shackle setup and no wrap bar. it flexed VERY well.
They flex alot better than most would think and do not need alot of weight. in the truck above all he had was the gas tank moved to the rear and BARELY had a bed on it for normal wheeling . Id trust the f150s alot more than the mazdas strength wise too.
