Gonna take out the 3" body lift and replace it with a 1" body lift that I made on the lathe out of some aluminum and polished

go ahead and use 1/2 inch grade 5 bolts with nylon nuts. OH and get new body mounts if they werent replaced when the body lift was put in.
my body lift came with 1/2 inch bolts but every other one ive seen has had 3/8 inch bolts which is pretty scary if you ask me
