9/16-18 x 2 3/4” Rear Wheel Studs – Dorman – 610-188
Those are the ones I used, came from O'Reillys.
I'm running steel rims...The length you need will determine what type of wheels you're running.
If you run aluminum rims, you want longer studs so the lug nuts have thread contact thru the nut hole or almost bottoming out in the chrome enclosed type nuts. Some aluminum rims have a thick lug base and therefore the nuts don't have as much grab to hold on to.
