A/C condenser...

[Rich May]

Just like the stock one? Maybe, because technology has moved on from a 40 yr old design.
I posted a pic of the NAPA unit. I see no reason it won't fit.
As for re-using the old part...Were you going thru the system due to a failure? If so, there's no good way to clean the tubes.

I only took mine off because I was replacing the radiator and figured I'd repaint the core support. Seemed like a good time to put a new one on but I just repainted it and put the original back on.
