I have a 79' C20 with 9 leafs in the rear. I was wanting a smoother ride, so I'm wanting to remove a few leafs. I heard theres a pin in the middle of the springs that I have to torch off to remove them. I don't have a torch, so is there any other way to do this? (saw, ect...) And is it a bolt in the middle or some pin I hear about? Thanx
