I've been poking around on the site looking for the info on converting the drum spindles to disc. I found info but the amount of metal to remove from the top boss on the spindle does not seem to be an exact measurement. The last one I read was, take off about .610 of an inch The info also said that you can use a hack saw and grind it flat. Seems to me that it should be a machine shop job so there are no un even surfaces for the caliper bracket mounting.
Has anyone done this? I'd like to hear from you!
