1965 Dodge Dart Charger

I can't remember why what type of fins or not went on the brake drums. I know in 65-67 most of the 9" had no fins at all on the front

The finned 9" drums were mid-'70 thru '73.

(some had springs wrapped around the drum)

Anti-squeak noise dampers. P/N 2266 298 (for 9" drums), standard equipment starting in '62 and running through '70 -- there's no groove for the noise damper on the finned '70-'73 drum.

and for the 10's some of them had a bell shape

Flared-rim 10" drum, rear only, for improved water exclusion and heat rejection. Don't recall what year that started on the A-body, possibly '70can check next time I'm near my ESF collection.

a few had fins and mostly on the rear

I am pretty sure A-bodies never got finned rear drums.

Now ask me about any glass from ma mopar from 1972-2003

OK: How'm I going to find a good American-made DW1057 windshield for my '91 Spirit?! Everything's gone Chinese, and even if I manage to get one without optical distortion, it's a safe bet the Chinese auto glass makers cheat and lie on their safety standards compliance "certifications" just like they do with headlamps, brakes, tires, etc. (PM me if you can help; I don't wanna severely hijack Ulf's thread)
