Another unknown for me which years had this. Assuming 88 and up and also assuming that anything from a GPHK body will work, but I personally do not know. I also have a thread for a set of early model spindles that have the bolt-in hubs and use the 10mm bolt to affix the brake caliper. If you have the spindles, K frame and control arms, let me know. I have leads on the spindles and plan to be at Cecil in a few weeks, so I may be able to pick things up if I make it there but I can't confirm that yet.
