my brother is keeping the small bolt pattern on his barracuda, does any one know if there are 3" studs available? what size knurl? we pulled it apart today, id like to go with a 1/2" stud instead of the 7/16" for strength, but the hole only looks about 1/2" in the axle flange. my own cars i swap to bbp, but he wants to keep it sbp. what are the options here? anyone ever redrill the axle to run a stud with a larger knurl? or is there a direct fit 3" stud?
