Truckfarm72, I know this is an old thread, but if you’re still around I have a question about the spring and hanger swap as I also have a broken hanger on my 63 k10. If using the 73-87 hangers and 88-98 springs, which shackles would I use, the 73 or the 88? I like the idea of losing the block but wanted to make sure the ride height stays the same. Thanks
