Ill install disc brakes also at the rear part of the car. Yesterday I discovered that I need longer lug studs. Today I ordered 10 moroso studs With knurl diameter of 0.685 inches and 3 inches in length. Im not sure if the studs will fit, but I took the chance . Rockauto sells studs with 0.625 in diameter. My 63.5 Galaxie has small bearings and 28 splines. Someone knows what is the the correct knurl diameter and if the 0.685 studs can be used?
