The bolt size of the 2 bolts that hold the brake caliper on the hub itself? I have the upper control arms and the rotors and all but I'm missing is the 2 bolts...thanks
 
I could, if we knew what year, type, brakes that your working on.

What do you mean by, attach to the hub? :dontknow:

Brake rotors, & hub, are attached together.
 
Thats the thing not sure what year they are ..4.5 bolt pattern though..took em off a 67' dart but I'm sure they were added later as it was a /6 originally .....And i mean the 2 bolts that attach the caliper to the hub ....like in this pic ...this isn't mine just an example ...the shiny bolt and the other

FYI
Those are Kelsey Hayes, 4 piston caliper, disc brakes, used on the A body cars from 65-72.

And they are 4 inch, small bolt pattern, NOT 4 1/2 inch.

And the caliper mounts to the Spindle, or knuckle, as it's can be refered to, also, not the Hub.

Those are special bolts.
A member here, Hemidart67 has repoped them for sale, but he now might be out of stock.
Do a search on him.

But they are 7/16 x 20 x 1 3/4 inch in length, if you can find regular grade 8 bolts to use, in that specific length, and diameter and thread pitch.

Look here.
I'm going to bookmark his posting, for my future reference, also.

If you measured, and are indeed 4 1/2 inch bolt pattern, then someone had a machine shop drill the rotors and hubs, out to that bolt pattern, or bought Ford Mustang rotors, and had them remachined internally, to be used on those Mopar spindles.
