Camaro core support

[Groyd]

I picked up a frame from a member here who had done a '74 camaro subframe. The bottom of the frame horns are even, but it's higher on the drivers side where the power steering unit is to accommodate the top bolt. When I tried to put my front clip on (after trimming too much of the inner fenders) the drivers side fender is touching the frame up front at the core support and not allowing the fender to sweep back to the firewall at the bottom.

Any suggestions?

I removed the inner fender bolt and rivet that holds the bracket to the core support that originally bolted the front to the frame.

It's a 1957 chevy truck.
