Bumping the thread here, I ordered the C-Body Sedan weatherstrips from a site known as AMS Obsolete. Worked perfectly with my application, I installed the cat-whiskers on the 2 front doors, and will do the rear ones tomorrow most likely.
(I ended up confusing them at first and snipped the end hooks off the right side door, but we'll pretend that never happened...)
Also took the time to lube up everything with some WD-40 (I also have some Lithium Grease somewhere, which I might end up using in place of it).
I would've taken pictures of the process but I forgot due to being elsewhere, remind me in the thread and I'll showcase everything I did.
