I have a 2003 Pontiac Grand Prix with the gtx package on it from SLP. I was driving and had three of my wheel studs randomly snap so I’ve been trying to replace them, problem is with the gtx package they upgraded the suspension so the original wheel studs for the other trims do not fit. Just wondering if anyone could tell me what size studs I need.

Why can't you measure any of the other studs?
Had a buddy take one to measure it at his shop and see if he can find them
