OK, I had to do a whole lot of browsing to find this information, so to hopefully save people some time in the future, I'm going to completely ignore part numbers and links from online stores because most people should have a local place they can get their nuts and bolts. This is all of the stuff I'll be using on my 83 Mustang and should be everything anyone needs to know in order to buy new hardware:
For this project I've chosen to use Grade 10.9 steel (Gr.8 if you're using the imperial system) nuts and bolts Ford uses this hardness as standard hardware.
These specs should be good for 79-93 Stangs, but I'm uncertain about the 94-04s - IMO, I think they should cover those cars as well but I right now I can't be certain.
YOU ONLY NEED ONE GROUP OF HARDWARE, BUT YOU HAVE TWO OPTIONS TO CHOOSE FROM: FLANGED NUTS AND BOLTS, OR REGULAR NUTS AND BOLTS USED WITH WASHERS:
I see no reason for these specs not to cover all 79-93 Mustangs, but I'm not sure if they'll work all the way up to 2004 or not, so please double-check if you're working on any 94-04 Mustang.
I HAVE NOT USED THIS HARDWARE ON THE 94-04 STANGS, THESE ARE JUST MY THOUGHTS ON THE MATTER:

NOTE: I highly recommend using some sort of anti-seize (ie: Copper Coat) on the threads before bolting everything down.

I HAVE NOT USED THIS HARDWARE ON THE 94-04 STANGS, THESE ARE JUST MY THOUGHTS ON THE MATTER:
- Rear upper control arms can be exchanged through 79-04, so this hardware should work there.
- Rear lower control arms are interchangeable as well, so this hardware should work through the 79-04 years as well. Some companies, like Maximum Motorsports have different LCAs for 79-98 & 99-04s, so I'm not sure what's up with that.
- Front control arms went through changes between 93 and 94, but 94-04 front control arms can be used on the 79-93 Mustangs, so I think that the front hardware specs should be OK for all 79-04 Mustangs.
