Hi. Trying to get a rear wheel with full width hub off a 73 Rickman Zunbdapp MX. It will go about one inch out at the moment. Normally it should involve driving the axle out with a drift. The question is from which side - both ends are threaded. Limited experience here as the rear wheels I took off in the past were conical hubs. Just don't want to break anything or screw anything up here. Can you help ? Thanks - Gord
