I found this on eBay:

Does anybody know what it will fit, the part numbers are P/N3010077 & P/N3010078. A big block, small block or both?

No big blocks with air in 67. It's a small block A/C setup. I don't know if it's from a Camaro, or not. Looks the same as a 67/68 Camaro setup but I don't have a cross reference to those numbers handy.
