ARP sells them.Do you want to stay metric or standard.
Metric part #ARP-100-7708
Standard part # for 7/16 thread ARP-100-7701
Those are Summit part numbers.
Yes I seen those on their site but they did not say the lenght, but in the pic ,they look long enough...I will use what ever I can get in my hand the soonest...
need to get the car out of the garage,,,soon....
if you read the discription for each stud set it has the underhead length listed in metric ,which in your case the longest they make is is 2.850 from the back of the axle flange (3" studs)
