I have had a heck of a time finding front wheel studs for 1967 Lemans drum brakes. Dorman sells the 610-114 as a 65-72 lemans drum brakes stud, but they do not really fit. They have no shoulder for the drum to ride on. The brake drum has obvious play side to side and up and down.
I have tried the new CPP assembled hub with studs -- same problem. The studs lack a shoulder for the drum. The drum can rotate from side to side on the studs. Seems like this could get off balance.
I went through the Dorman catalog and found a 1970s Dodge/Plymouth part that had the same knurl size, a shoulder for the drum (within .010 inch), and was only a little longer (but still seems to fit under the Rally wheel lugs). Dorman 610-168. Seems like it should work.
Is there a better solution out there I haven't found (short of converting to discs)? I am pretty far down this rabbit hole already.
- The first picture shows the wheel studs marketed as a replacement ... notice the play the drum has on the studs.
- Second picture OEM knurl diameter
- Third picture shows Dorman 610-168 Dodge knurl diameter
- The last picture shows the OEM 67 Lemans stud, the Dorman 610-168 Dodge stud and the aftermarket replacement Pontiac Lemans drum stud Dorman 610-114.

Your drum should center on the pilot of the hub, so the replacement studs should work fine.

CPP hubs are trash - stay away.

Factory drums and hubs were swagged together. That's why the high shoulder. And this makes for a much truer running unit, as the drum gets turned while attached to the hub on the brake lathe, making it concentric.

I also ordered the Ames ones to try.
I think I like the Dorman 610-168 better (catalog says for Dodge products). The knurl is the right size. The shoulder is about a perfect slide fit into the aftermarket drum. No play.
With all five studs installed it takes a few love taps to get the aftermarket drum on. The Ames studs have a little bit longer knurl than the dodge studs (but shorter than the OEM shoulder) to press partway into the drum.
Just writing this in case it is helpful to anyone else.
Left stud is Dorman 610-168. Middle is OEM. Right is the Ames stud for the studs that drums press onto.
