Need direction on mounting large A6 a/c compressor

[72farmer]

I need someone to point me in the right direction on a a/c compressor mount. I just bought this 72 with factory air. It also has the old compressor. The PO said the a/c was working until he put a different engine with taller valve covers.
Now the compressor is just laying over to the side and I need to find a mount for it. The small block engine has a short water pump and the alumiumn heads has the threaded holes in them for a bracket. I hate to start ordering brackets only to find out they will not work. Any recomendations without spending a lot of money on a complete system? I don't mind getting a smaller compressor if need be. But I had rather use this factory style one I have.
