Trouble finding the right replacement wheel stud

I believe the hubs and drums are from a 35? several of the studs are stripped and I figure better safe then sorry. However I ordered one replacement from macs only to find its the wrong size? cant seem to locate the right ones?

dimentions are

over all length 1.79"
shoulder hight .56"
shoulder diameter .63"
thred hight it roughly 1"

any ideas? the macs specs are misleading as there stud (part # 68-1107)
specs say Hub Bolt - Front & Rear - Straight Sided - .56" Shoulder X 1.56" Length With 1/2" X 20 Threads - Ford Passenger

However my measurements are

over all length 1.54"
shoulder hight .56"
shoulder diameter .56"
thred hight is roughly .77"

If you have one out for a sample that would help.

You might check some of the early Ford sources too assuming that it's a Ford.

 

yes it is ford

Unfortunatly my Napa fellas werent very good at there job

 

is it acceptable to press in a knurled stud in a smooth hole? (thats what she said)

Seems most newer studs these days are the knurled type
