Your local parts store can hook you up with brand spankin' new unstretched,unfatigued,unrusty,unmessed up thread u-bolts for not a whole lot of moolah. Take yours in or measure your axle diameter and figure how long. I get mine from Napa(always cut old ones off)

thanks. do you know the size of bolts an Eaton rear k20 would need? I've got super longnsprigs from my 4 inch blocks. I'm putting 4" springs so I should just need factory length bolts. do you know the axle tube diameter?
