Lug Stud Recommendation

[Kansan]

I need to change out four left hand thread lug studs on the driver side rear axle on my Cuda. Apparently, someone has swapped out the axle shaft because the left hand threads were long gone by 1973, based on what I hear. Anyway, the lug studs have a knurl diameter of about .65/.66 and the studs at O'Reilly were way too big. Can anyone recommend a good place to find the lug studs I need. Thinking of doing to the Dodge dealer in the morning, but not sure if they can help.

Thanks,

Kansan

When installing the studs don't be tempted to use the threads and a wheel nut to install them! I use a vise (Harbor Freight) and a deep socket. It takes awhile and isn't quick, but it ensures you don't stretch/strip the threads. You don't want a wheel and tire coming off!

I assume one is right hand? Or you have one? You said four and not five.

Years ago I bought my lug studs from Year One. I'm sure other sites will have them also.

You are correct, Sir!

I just reviewed the 1970/1 parts book in section 22-05-14 and its looks like spaghetti to me. It is unclear which studs are the front and rear (heavy duty) 11-inch in drums. To clarify, I refer to option B11 "Heavy Duty Manual"

If thatt is the same part that O'Reilly calls for, then it's too big with a knurl diameter of about .69x (don't recall exactly).

If I can't get the correct stud by part number or by telling them what I want, I will take an old one and my digital micrometer with me to the Parts Store and go through their Inventory. Works every time.

This is what I come up with. I even went to the Summitt website and double checked dimensions. I think they will work.

The knurled section is smaller (.665" vs . 675" for the Dorman), so should work!

The knurled section is smaller

.665ish is what I measured on the one that I removed from the axle. I'd get a thousandth difference when I measured multiple times....
