Started to work on the Geo disc conversion on my 58 and found things I wasn't expecting based on what I had read in advance. I started on the driver's side and it still had the left handed studs. First of all, after pulling the wheel, the brake drum wiggled and the studs did not appear to be the swedged one I had read about. In fact the drum was on the outside of the studs and just wiggled off. In fact once the hub was off, a fairly easy pop with a hammer and the stud piped out. Then with the dust cap removed, a PO at some point had bent up the lip of the washer to prevent the hub nut from spinning. Then there were 2 of these nuts with this bent piece between them. Is that correct? Eventually I got it all out along with the bearing and then the hub easily pull of off with my hands. I never had to use the 5 arm hub puller I bought in advance just for this process. Did a PO change something or were things different for a 58 then I had read? I'm confused. I eventually got the brakes and back plate all removed. A light tap with a rubber mallet separated the backing plate from that center cylinder piece. I'm assuming the way this thing goes back together is that center piece, then the special made Geo caliper bracket?
