Try 1/4-28 UNF. They look like the bolts on a fan hub. I think Ford may have made his own special bolts but, I recall using 1/4-28 bolts.

Elwood, The hub bolts in all of my -42 - 48 fan hubs are 12-32. You should be able to get these at any decent hardware store in your area.
If not, McMaster-Carr is your friend :)

Looks to me like the back side holes are square like for a carriage bolt. I can't tell what the application is but finding fine thread carriage bolts would be difficult. I bet coarse threads with lock washers and Loctite would suffice.

Ok, I just zoomed in and the holes are round. disregard what I posted. Should be a way to delete a post instead of leaving no text.
 
ok guys, 12 by 32 they are, but where on earth can I find 2 1/2 inch long 12 by 32 bolts

I checked and even McMaster-Carr doesn't list them. They have 12-24 but not 12-32. If THEY don't have them, I simply don't know who might.
Do you have a lathe? If so, they'd be easy to make.
 
Would it be possible to drill and tap those holes for a different size fine threaded bolt
that is available?
 
Your not going to find them anywhere new I can promise! I am having them made currently

You can always tap the hole to a 1/4-28 which in reality isn’t much bigger
 
Sometimes you have to improvise. I have used all thread and then used red loctite to hold a nut on for the head. The nut can also be welded or soldered on. Fastenal can most likely get you what you need.
