Hey Robert, yes factory air unit on the firewall. Brackets on the motor are there but not sure all of them. The base heavy cast iron bottom bracket and one that must support the back of the compressor. It is a round casting that resembles a round compressor. If your a SG-1 fan it looks like a stargate. The firewall unit is definitely factory, the (I think it's called the accumulator) the thing that separates the gas to liquid like bottle assembly is mounted up on the radiator core with all the lines still running to it. Other than a quick look it looks intact. I'm just wondering what it might be worth? I'll be removing it regardless. Mark L
