If you want to be 100% safe and not have to worry about design a whole lot just use 1/4" steel and grade 8 bolts. But it is just easier and cheaper to just re-arch the springs or overslung the axle. Overslunging that axle will drop your height about 2-3 inches roughly.
My buddys have told me to do the overslung axle my only thing with that is will it affect anything? I dont wanna tear anything up or mess up how well it rides. Would that affect my drive shaft in any way? Idont want to be blowing out u joints due to a bad angle with the drive shaft i already need a new pinion bearing in the rear end. If i do flip the axle ill replace that bearing while i have the whole rear end out. But thanks for the info this could save some money since i wont have to buy anything!
