I changed the front leaf spring hangars on my stepside.It came with grade 8 bolts in the kit so i just put them on with a little dab or loc tite and torqued them down to the reccomended specs.I also replaced the rear crossmember in the very back , the 1 i had had a big bend in it and i bought 1 from a member here.Ground off the rivets, put the new 1 on and did the same, grade 8 bolts and loc tite and torqued the bolts down to 50 ft lbs.But thats about it .
thanks
