For some reason I guess I didn’t comprehend what you were looking for. To reiterate I have a 1980 TA that originally came with a NA 301. While I have removed the original 301 I have lots of under hood photos of the original 301 engine installed as came from the factory. I could post some clean under hood pictures of the AC compressor mounted. I still have functional factory AC so if you can tell me what specifically you want shown of the AC dryer assembly I could post those as well. The car is an 80, not an 81. Normal carb, not EC. Let me know?
I also have a reprint of the 1980 GM Firebird assembly manual. So it’s possible what you are looking for is in there. If so I could scan and post from the manual, but the quality of print is not great.
