Rear Cast Iron Brake drums too big for Wheel

[larrys40]

post some photos... I've used all the cast iron drums before from Brattons, snyders, Randy Gross and have mounted many and not had a problem. I would make sure your drums/hubs are properly mounted ( surprising but I've seen some not done properly) and just taking the hub/drum and setting it inside the wheel it should fit. The wheel actually should contact in 3 different areas, inside of wheel at hub area, outside hub of wheel at drum, and lug nuts if all properly seating.

check it out closely. put grease if you need to inside the wheel at points and see where it's hitting. Look for witness marks.
post photos and reply back please.
