The upper hinge is not in question. The large washer is required because of the large square holes in the hinge and does not cause any problems. This same size washer does interfere with the flanges of the lower hinge however as shown in my pic. The marks shown are from the 1 1/8 washer on a stripped and freshly rebuilt/ primed lower hinge. I did not notice this until I removed the bolts after a test fit. Someone out there must have run into this?
