I'm working on a 69 custom S and I rant into a snag when replacing the rear axle bearings. I purchased new axle shafts and new bearings while I'm installing rear disc brakes on my car. I didn't take a measurement when pressed off the old bearings off so when I pressed the new bearings on the new axle shafts I pressed them on as far as they would go which in looking at it now was probably wrong. When I bolt the retainer plate to the axle housing then try and assemble the brakes the new rotor hits the caliper bracket. Does any body know what the stock distance from the outer axle bearing is to axle flange?
