Have you ever had the door inner cardboards off? Those spring clips are essentially the same as the one on the lower windshield trim except the windshield trim clips are a bit larger. .
Pretty much like this one.
I'm not totally familiar with your specific car but as I understand the drainage openings for Mopar rockers are the ones I kinda circled below. Not at all sure what the round holes in the rear of that rocker are for.
Actually the parts store I most often frequent does indeed have a portable comparator and I've known them to go to the car to check - although typically an autobody shop.
Not saying it wouldn't be, personally I don't give a **** if it breaks again in another 54 years, it won't be me fixing it.
:lol:
I will say though, if you don't remove the hinge, (like I didn't), it will likely be a whole helluva lot easier to put the rivet in than the roll pin.
It looks like you have what the factory installed. That little chrome/stainless strip has some fuzzy 'whiskers' along the inside edge against the glass. They're sold and marketed as cat whiskers. No rubber gaskets/seals on that vintage.
If it runs good and the doors close AND you can buy it for around 250 bux to use for a daily driver, it looks like a decent buy to me. For anything else I'd say it's a parts car and the value may increase if you need some of what it has.
Most from that era are a one piece unit, the mast, base, and lead in cable don't separate so removing/reinstalling the antenna is not a practical thing to do. You may be able to make a later unit with a removable mast work but I've never tried.
