Thanks to Harold for putting me on the thread. As stated, according to Pontiac-printed info, there was a restriction on V-8 with M/T and A/C.
Phillip, I'd love to see a copy of your PHS invoice! If you can't post it here, you can email it to me at jamesrotella@cox.net. I'd also like to see a picture of your cowl-mounted data plate if possible.
