Rear Shock Won't Mount to Shock Mount

I have modified many shock mounts on many rear ends. The best way to do it is to let the shock hang free from the upper mount then cut/heat/bend the lower mount stud bracket until the shock slips on nice and smooth. I have sometimes "cut" a slot in the bracket (spring plate) so that I could bend the portion that holds the shock stud then when I get it just right I would re-weld the cut . Maybe someone has an easier way??
