OH .... 
.... OK .... thought you were speaking about wheel studs, then it sounded like you meant the 8 or so studs that secure the drive axle in the floating hub of your 3/4 tone axle, and now ..... I'm believing that you mean the 4 bolts that bolt the brake backing plate to the end of the axle housing?
They are usually funny looking heads on them, kind of squished looking long oval heads. Often called "T-bolts", maybe 3/8" or even 7/16" diameter? That picture is a 9" Ford rear in a F100/150. Your's is maybe a Dana 60 with floating hubs.
Do you have one to gage thread diameter, etc?
Ford Racing M-4002-B - Ford Racing Brake Backing Plate T-Bolt and Nut Kits - Overview - SummitRacing.com
Those above are 3/8-24 NFT 1.30" long Ford bolts for the 9" rear sold by Ford Racing M-4002-B available Summitt, etc. They may not work for your Dana? '
You are right, not as easy to find. Not enough room for a bolt's head.

They weren't cheap! Might be some cheaper standard ones available .... but the likely are stout.

I assumed after I read post #9 that the T bolts are what you wanted, but didn't wanna chime in till you confirmed.

1973/79 Ford Light Truck Parts Catalog sez in the rear axle parts lists for the 9" rear axle:
To obtain the correct parts for 1979, you must measure the backing plate bolts to see if they are 1/2" or 3/8."
-----------------------------------------------------------------------------------------------------------

387997-S (replaced D8AZ-2248-A) .. T Bolt-Axle Housing to Backing Plate / 3/8" -20 x 1 23/64" long / Obsolete

I'ld use what fits the holes.
Using 3/8" bolts in 1/2" holes will allow the backing plate to rotate some forward at first brake application until next time you back up and hit the brakes, when they may allow it to rotate backwards when brakes are applied ... and so on. This movement will not help the brake lines that have to flex to go with the plate and the bolts will soon be loose .... at best.

The only set of 1/2 inch studs I've found are only 1.00 long. I don't think they would work. The OEM parts are 3.77 a piece but I don't know if they come with the nuts or not.
Numbers does your parts books show a seperate part number for the nuts or do you know?
