COMET CENTRAL

Hey gang - I've got a radiator in my '61 that fits & sits like stock but has a driver side inlet, passenger outlet. Was in there when I bought it. It's OEM from something. Height/width look right, mounting holes for Comet were drilled about 1" lower than teh original locations on the brackets.

Any idea what this unit might have come from? Or other radiator ideas welcome, I just need something with a DS inlet PS out. I'm open to a little cutting if it makes sense.
