Need to install A/C compressor on 6.1 in a '68 Barracuda

I need to install an a/c compressor on a 6.1 in a '68 Barracuda. It has a stock K-Frame and Schumacher engine mounts. The a/c compressor on a 6.1 hits the engine mounts. Also, on a 5.7 timing cover truck swap, the a/c compressor and alternator hit the hood when you try to close it. Does anyone have any ideas on how to solve the problem? Thanks!
