Are old A/C bracket mounts needed for Sanden compressor?

My 67 Barracuda came with factory A/C. I have removed the compressor for now, but I will eventually be going back with a newer Sanden compressor. Do these retrofit compressors use existing brackets, or do they use their own.

I need to pull the water pump, and now is the time to remove that front bracket if it is not needed.
