American Eagle 15" won't fit my 72 K10???

[Lugnutt]

I just bought a set of 15x10 6lug 5.5" American Eagle #058 aluminum rims and they won't fit around my 72 K10 pick-up front stock disc brakes. Mounted-up the rims with 33" 12.50's tires and it was looking good until they tried to mount the fronts to the truck. The barrel of the rim locks-up around the disc brake mechanism (not enough diameter room inside the rim for the brakes). Has any of you ever had trouble with 15" American Eagle wheels mounted to my year of truck? American Eagle says this is the first time they have heard about this problem with their rims. I've owned the truck since new and I KNOW these are the stock "Delco" brake system.

Thanks for your feedback
