Yes, I had a similar problem with my '34 front wheel drums. The B-1107 studs offered throughout todays part suppliers are not correct. Their sold as fitting both front and rear....they do not. As the following two parts breakdown pages show, the measurements for the various years are different compared front to rear....year to year.
As you can see from above, an original Model A Passenger car front drum takes a stud with a shank diameter of .62, shank length to swedge is .38. 1928-35.
Using todays available B-1107 wheel studs in my '34 front drums, this is what I found:
No way are you going to swedge that much shoulder down! The overall length is way too short, plus the "head" is not 1 inch in diameter, making a lot of play against the drum "shoulder" its meant to sit against:
My alternative was to purchase a Model T (#T-2888) rear wheel stud bolt for my '34 front drum:
It has the right shank size. It swedged in just right. Although the thread length is about one cut thread short, it's not bad. The "head" size was a better fit than todays B-1107's..... however I still had to spot weld a couple of points on the head to tighten up the twisting play:
That's better than welding the drum and running the risk of warping it.
Now, I don't know what you're going to find for your particular drum you've got? But a Model T rear stud works well for an original '28 to '35 front drum.
