72 Bronco Wheel Studs. Shoulder Width Too Short.

[Ark Bigfoot]

Should have said shoulder Height... I went to NAPA and got two wheel studs to insert into my front spindle. He measured it and said that's what his system says to use. I put them in and now the shoulder is about 1/4" high versus the original studs shoulder height of about 7/16 inch. The drum goes over but shoulder lacks about 1/4 being as tall like the others. Is this an issue which I should look for some like the original. Since I have 3 of the original perhaps that will keep things in line. I am using a new Raybestos Drum.

That's your hub, not your spindle. Anyway, the overall length of the studs appear to be the same, I think you'll be okay.
You did press them all the way in, right?

I bought a Lisle Wheel Stud Installer and tightened as far as it would tighten. "no gap". The new studs don't come flush with the top of the drum as the old one's do. About 1/4 shorter. Another picture shows it better.

Wheel studs come in more than a hundred sizes, go to the NAPA site and take a look.

Your problem is that you have studs with a shoulder length that is "too long/too short". All of the different dimensions for a stud is listed on the NAPA site the last time I looked for studs on my race car.

As far as "coming flush with the drum", I do not understand the importance. The stud "shoulder only pilots" the drum to be centered. The correct term is called Lug Centric.
