I got the vin from my frame and found out it is a 55 frame. I am building a 56 though but I don't think there will be a problem with that........I had a question about the rear leafs, mine has the main leaf, 1 full spring, 1 next with brackets attached to each end, 1 full , 1 shorter next with 2 more brackets attached, and then the shortest. I did have one about 3 inches long that the u bolts went against but I am flipping the axle so I don't need it. I bought the liner for the springs, and a new center bolt. Should I remove any springs or keep them all. How many did it have originally.
