Just got one for free from my boss- its got over 200k on it (w/origional clutch!) got it running- now i need motor mounts, ball joints, sway links that ive found so far. Its a fun car to drive, I hope i dont get into too much trouble with it.
For the front end parts, here's a listing of the parts from RockAuto, almost all Moog:

If you're doing the lower ball joints, do the strut rod bushings at the same time (they're a LOT easier to get to with the LCA out!). Front bushings - ONLY FORD. Repeat, ONLY FORD. Do NOT try after market - NONE of them last!
Luckily, if your ferrules are in good shape, the bushings are only about $40 plus tax from Ford.
You'll want:
E9SZ3B271A front bushing at frame
F7SZ3A225AA rear bushing at frame
I paid $41.92 including 9% tax for two each at the local dealership, but had to scavage ferrules out of the wrecking yard (mine were mushroomed and no good due to someone previously overtightening the nuts to keep the front end from clunking ... )
Check here, there's usually a current RockAuto discount code good for 5%, which can help offset shipping charges.
DO check against the local prices - sometimes, you can buy locally for more for the part, but less once you figure shipping (not often, however!)
For almost everything else but the strut-rod-to-frame bushings, Ford or Moog/TRW. The hubs with the bearings? National or Timken (since I can't find Ford except at the dealership, and the bearings are either National or Timken in them anyway ... )
