I like your convertible project and your thread. I like Mustang stories that go decades back. I'm in the north part of the state just 3 miles south of Tennessee state line.
The mirror on the drivers door is an original fancy or "deluxe" mirror that came on pony interior Mustangs for sure. If you don't see the control cable for it, it should be laying down inside the door. The short "AC" console was cut and capped at the factory for Mustangs that had a factory installed (in most cases) and sometimes at the dealer. The under-dash unit that in 1965 Mustangs look just like 1964 Fairlane under-dash units. Do you have all of the under hood engine parts for the air conditioning? AC working on the old vehicles adds ~$4000- to their value when you are putting classic car insurance like Hagerty on it. Hagerty is really friendly about insuring unfinished projects.
Me and my younger brother have been working on the 1960's Mustang since the early 1970s when we were young teenagers. This past Tuesday, we started back on the restoration of a 1966 Mustang coupe, C code 289, auto transmission, power steering, air conditioning, pony interior with a vinyl top. It is going back near original. The junky, leaking hydraulic assist power steering is coming off. Electric assist steering is going on. Upgrading the AC to all new components with a restored under-dash evaporator unit. Under the hood it will have an upgraded compressor much like the one on your foxbody, a Sanden SD-7 dual belt. I'm not intending to step on your thread, just give you ideas and info about the mirror and console. Keep putting your convertible back together and address the couple of paint issues at the end of your project. There are some little tricks, for the lack of a better word, that you can do to fix the chips.
If you go to our Facebook page
https://www.facebook.com/profile.php?id=100010788463239 , you can see a few pictures of the Tan (Sahara Beige) 1966. The AC units in the 1966 were narrower than the 1965 units. It is in a picture or two. On our long FB page, there is also a 1965 coupe that we are in the middle of a restoration. Also for any 1967-68 people reading this, we just finished installing aftermarket AC on a gold 1967 Fastback Mustang.
If you want to see how I polished some ss trim on a 1970 convertible that we restored, on our Facebook page, scroll down to July 26th 2019 and there is a short video of me polishing some old stainless steel windshield trim. I made a buffer out of a "thrift store" electric motor. Online I purchased a mandrel to attach to the motor shaft and also purchased a buffing wheel and several different grades of buffing rouge. Start with the coarsest rouge and work your way up. One piece of trim hade some scratches, so I used 1500 wet sand paper and water sanded it first. I'm not a trim restoration guy but our set-up worked ok.
If you have the under-dash AC unit and the AC engine brackets, I can walk you through installing and upgrading the air conditioning. It would be nice to have on the sweltering summer Enterprise days.
