64.5 Ford Mustang

I have a 64.5 Mustang 260 with generator and power steering with an Eton pump. I am attempting to install origional factory air conditioning. I have mounted the compressor but now the Eton pump cannot be mounted back because the compressor extends to far. I am told that a factory Ford pump with a slanted reservoir may correct the problem or a remote power steering reservoir may also correct the problem. Does anyone know the correct way to fix this problem.

Check with some hot rod shops or hot rod/street rod parts stores.They
might have something that can be of help.
