What length for long wheel studs

[01XtremeLT1]

OK this is probably a dumb question but I'm asking it anyway.

I'm in need of replacing the wheel studs in the 8.8 when it gets redrilled to the 5x4.75 pattern. My question is, with the stock stud being 2" under the head, How would I determine the correct stud length to be legal using open ended lugnuts.

thanks!

I think its 3" but cant remember off the top of my head..
Someone will chime in..

to be nhra legal you have to be engaged into the threads the same distance as or more as the distance of the stud
( example a 7/16 - inch stud must be thoroughly engaged through the threads in the hex portion of a lug a minimum of 7/16 - inch, to be legal )
