I've looked everywhere on this site to see if anyone has posted the thread size, knurl diameter and shoulder size of the wheel stud but I couldn't find anything. Basically I am looking to change out my front wheel studs on my 67 1600 to something thats a little longer so that I can get the lug nuts to thread more of stud. Looked a Dorman Products (
https://www.dormanproducts.com/catalog/ ... _Part2.pdf) but I'm not sure of the exact specs. Does anyone have a clue?
Any help would be greatly appreciated.

There was an excellent discussion about this on the "Roadster List" yesterday. Mike is a member here and I hope he does not mind me pulling the information and putting it here. I plan to add it to the wiki-tech section once I ask him. Here is his thread.
Just wanted to give the list and all those who replied to help, an update. I
found longer studs (1 3/4") that fit and provide me with a full 3/4" of thread
tightening with the 15" Panasports I bought. The nuts still have ample space
left so they won't bottom out. So far I'd say the length is perfect, at least
on the axle. They're listed for the ' 60 to ' 82 Corvette and ' 67 to ' 69
Camaro.
Here are some specs I researched if they might be useful to anyone:
Nissan Stud Part # 40221-14600 Stud length 1.277" Knurl Dia. - .468
Knurl length - .25"
Dist. from head to end of knurl - .34" Shoulder length - .5" Shoulder Dia.
- .45" Thread length - .75
Moser part #8259 7/16-20 x 1/3/4" ('60 to '82 Corvette, '67 to '69 Camaro)
Jegs, Summit, Moser Engineering
Dorman #610-259 ('60 to '82 Corvette, '67 to '69 Camaro)
Specifications:
Head Code: 259
Knurl Diameter: .475 in
Thread Pitch: Right
Shoulder Length: 27/64 in
Thread Size: 7/16-20
Length: 1-3/4 in
Type: Serrated Stud
Features: Zinc plated for corrosion resistance
I didn't have to pull the axle but it still took 3 hours, not too bad.
Tommorow the fronts!

I would be VERY careful when using the thread count method for shank type lug-nuts. It’s my understanding that the threads that count are the ones in the nut portion of the lug-nut.
For race prepared cars, they usually require "open" lug-nuts and that the stud protrude through the lug-nut.
I have seen shank type lug-nuts that the head popped off....and the wheel came off because the stud stopped just a few threads into the "nut" portion of the shank style lug nut.

I've heard that too, sounds like good advice to consider.
