Can't find an appropriate Buick or general old car newgroup to ask, so maybe someone here can help.
I've found what I think is a replacement heater core for my '63 Buick Riviera on eBay. It's listed with inlet-outlet dimensions, size, etc, and what appear to be original part numbers, but...how can I cross-reference this information from the eBay listing with official GM parts listings to make sure it's the real deal?
If someone told YOU that a certain heater core fit YOUR Camaro...where would YOU look to make sure before putting your money down? (Assuming you don't have this information already memorized...)
Thanks...
