Danny ,check and see if your pass side tail pipe is welded to the muffler ,curious.--steve.
How are your 3 flex lines ? ( front 2 calipers , 1 rear) I'd shelve the OE's and replace. Cool to say they are "original' but pedal stiffness will suffer if they got soft over the years. Mic your rotors and measure your drums to see if still in spec---repack your inner/outer front bearings. I'd also change the 90 wt in the rear end (add your additive) and the Munci. My front end is still tight, if yours is ,use a high quality grease ( I like red) and pump the old stuff out. Don't forget the steering gear box.
Shelve the belts (or throw the in your trunk for the shows, good conversation stuff) for Dayco cogs. Hoses also for that matter, or at least check at operating temp if they are collapsing. Rubber fuel line back at the tank.
No fuel leaks at the metering blocks ? While running spray a little WD40 (not a fan of water) around the base plate and monitor RPM to see if it's sucking any air.
All in all these are very simple cars ,a "little love" will go a long way with them. I understand the survivor thing, but if you plan on driving her ,make sure she's sound.--steve
