Studs are designed mostly with a course thread end and a fine thread end. The course thread always goes into the cast iron part and the fine end always fastened the hex nut. Are these the parts you seek:

9N-6345; 1/2-13 x 1/2-20 x 2.84 L, Drilled, 5 req'd.
9n-6346; 1/2-13 x 1/2-20 x 3.84 L, Drilled, 1 req'd.

FORD used specific lengths in all their fasteners, most in sizes not sold today so getting the LENGTH correct is important. There are a few suppliers that stock the odd FORD lengths, I had a list somewhere, so perhaps someone else will chime in.

27/32 is .8437" and is rounded off as .84, NOT a standard size, and .94 is 15/16 (9375") rounded off, and NOT a standard size today.

Perhaps you can do some more research in the archives and use hex head bolts to see what others used.
