Thanks for the replies and PMs guys!
My car doesn't have AC, so I'm not that familiar with those parts...
That said, a quick Googling found this:
https://www.camarocentral.com/1969_C...p/das-225u.htm
Anything to the info in that link on this? Any one here with an original AC '69 that knows it hasn't been tampered with that can confirm or deny? Thanks again.
Yes, once I confirm what this is / that it's a real and genuine NOS GM piece, then it will be for sale.
Cheers all, appreciate the help.
