Looks like a OE unit to me. Not all were stamped 180* and upside down. Some were not stamped all. EZ to spot a Chi-Neez one. half the cars restored now have the El cheepo ones installed.
Easiest way to tell is to compare the "Triangle shaped stamped in stiffeners. The repops are very sharp at the bottom with a distinct hard line, the OE ones have a nice smooth radius.
Next time you watching a auction on TV zero in on the under hood shots, you'll be amazed. [img]<<GRAEMLIN_URL>>/shocked.gif[/img]
