Woo Hoo, success!! Just finished, installed marlin crawler birfield reseal kit and did the vented brake conversion. Was able to get the studs out with just a hammer and lug nut. I had very minimal rubbing from the ifs calipers, so minimal in fact i just ground down a small amount from the calipers corner. Next i'll be installing the marlin crawler crossover steering. Just need the bracket for the steering box, doh, forgot to order it with the kit, haha.
