76 Duster Front disc wheel stud size

[awg329]

Due to wheel and spacer issues, i have to run 3" studs on the front discs of my 76 duster. Confused on the knurl diameter. Classic industries catalog shows .620, but the studs I removed measure .614 to .616. Looking at Moser 8010 or Moroso 46180 at Summit Racing. What fits best ?

Everything I see says .620, BUT keep in mind, the aftermarket may be taking for granted the holes are a little over sized from knocking the old ones out, so that may not have been the factory knurl diameter. If that makes sense.

Update- both sets of studs measured .622 to .623 ". I decided to use the Moroso since they had a longer knurled area and quick-start end. I was able to install them by drawing them in with a lug nut. I am using a 5/8 " spacer due to my wheel backspacing but I still had to cut about 1/2 " off the studs because the lug nut bottomed out before it was tight. So far so good.......
