ok my lingo may not be accurate but I was taking off my wheels on my samurai I just picked up so that I could check out the brakes. well, I need new rotors and pads on the front so far and I noticed when taking off the lugnuts that one was missing so I need new studs but along with that they are so short due to the new wheels that the lugnuts were barely even on them.
So my question is how long are the stock studs and the thread? Since I am replacing the rotors and pads I thought I might as well replace all the studs with longer ones instead of leaving them and replacing just one.

If you are going to put on new wheels, then just pound one stud out and take
it into your auto parts for a match up, add whatever additional length and your good

your correct I should have just thought to take the old studs in, thank you. they are just the wheels that came on it from the previous owner and as I was taking them off I realized the lug nuts were barely on.

If these are like the old "mags" that should use a sleeve type of lug,
I'm not sure if they are available in metric threads tho

 

If you want slightly longer then stock studs get some from the front end of a Geo Tracker.  I believe they are a 1/4" longer, possibly more.  Same thread and pitch, they will pound right into your existing drums.
