Pretty sure LH studs were never used on D27 or D30 axles. This appears to have the "outside" mounted rotors used in the conversion. Do you know if these are indeed the late CJ rotors or something else? Your choice of studs will be dependent on that.
This is the common D30 hub disc brake wheel stud:

As far as the above reference to Kaiser-Willys, I NO LONGER PURCHASE ANYTHING from there. It is almost all Omix-ADA and most of that stuff is absolute chinese junk.

Great info. I did the disc brake conversion using the 1985-1989 Suzuki setup and Brandon's garage brackets. I just went and got the studs you linked above. The knurled part seems to fit well enough to stop them from spinning when I tightened the wheel. The only thing is I can't get them to seat properly.

Here are pics. As I am sure you can guess, the silver ones are the new ones and aren't fully seated in the slot. Does this matter? Was the part I got above not the right one? Or do I need more torque to pull them in farther? I am using a powerful impact hammer (Milwaukee 18v Fuel), but maybe it isn't enough for this?

More great info. Thanks!

So I had more time to look at it today. I am just thoroughly confused. When I did the disc brake conversion, I didn't change out the hub assembly. I used a setup I found on 7-Bar Salvage's YouTube channel. It is some Suzuki parts and Brennan's garage brackets. The install went fine. I have take the wheels off multiple times and NEVER noticed loose lug studs. But there is no question the lug studs that came off were undersized. I think they are a .629in knurl diameter. Is is possible for a D27A to have a D30 hub assembly? I am going to check, but maybe one side is an actual 27A assembly with the advance threads as @David J. mentioned? Mine is certainly not threaded on the driver's side front.

I went and got some new ones based on the recommendation above (https://www.napaonline.com/en/p/NOE6411610?impressionRank=3). I pulled the hub and banged them with a 5lb hammer. There is NO way they could work in my setup a) because the stud head is too thick and therefore would never seat properly in the hole without sticking out and b) the part I have circled in yellow below gets pushed out when I put the rotors on.

below is that part I mentioned is too thick

So assuming that a D30 hub assembly could be on a D27A and that is what I have, is there a better lug stud that would work with the Dana 30, assuming that is what I have?

Thanks!!
