Need Help with 1982 Radiator

[Steve]

I read in another thread that there is no difference between SSP radiators and other Mustang radiators. But I cannot seem to fit a stock 82 radiator into a 1982 I am working on (CHP 0204). I don't see any evidence of damage or modification to the support area that would explain it. Yet with stock radiators the tanks are about 1" too high. The upper radiator brackets also don't match up directly.

Has anyone heard of this problem?
