AC underhood component upgrade.
The factory rotary compressor from a mid 80's dodge pickup is a little larger in dia, so cut and welded it to match a standard aftermarket Sanden compressor. I think multiple V8 vehicles from the 80's would have the same compressor brackets. it mounts the compressor just to the passenger side of the thermostat housing, and just clears said housing. Only picture I have of it at this time.
