454 engine brackets

[General23cmp]

I recently acquired a 454 that was in a 1970 Chevelle (not numbers matching, so don't worry), and it was configured to look original to it with the compressor on the driver side and alternator on the passenger side. I'd like to swap it around to make it look right for my 1972.

Does anyone know the correct part numbers for the alternator, compressor, and power steering pump brackets for a 454 engine to make look close (or just like) to original (compressor on passenger side, alt on driver side)? I'm not sure if the PS pump brackets would be the same. Also, does anyone know if a modern style compressor (like a vintage air system would have) will bolt up to a factory bracket and align?
