I seem to have determined the lug bolts in my wide 5 two-piece ‘37 brake drums are smaller in diameter than those in the one-piece hubs. Is this also correct for the smooth two-piece drums? If so, is it possible to use the ‘36 drums without fins on my hubs?

Ken: I cannot imagine Henry using two different sizes of wheel lugs in the same year. Measure again.

The lugs in my early ‘36 hubs measure 0.557 and in the late ‘30 hubs are 0.625. Which is correct?

All early Ford lug nuts are 1/2 fine thread with I believe a 13/16 hex socket size.

We're talking about the register diameter of the studs here.
Ken, can the drums or hubs with the smaller holes be redrilled to take the larger studs?
It shouldn't be too difficult.

Probably it is best to make sure the studs fit the drum then drill out the hub as required.

Ken Bolton...Ford used B-1107 studs with a .62 diameter on passenger and commercial rears in 1937 only. Ford also used stud 68-1107 with a .56 diameter from 1936 on into the mid-1940's on both front and rears during the wide-5 era of 36-39. It is very possible that you could have two different studs on a 37. 1936 additionally used rear stud part number 68-1118 which had a .50 diameter and is .12 shorter in length than 68-1107, so you could end up with two different studs on a 36 as well. Ford also used a different stud on the spare mounting flange. It would appear that there is no single "correct." Perhaps you could simply replace the studs rather than drilling?

Well, I reckon that blows me out of the water. LOL
