ARP lists the knurl diameter as .680 The replacement stud I bought at Advance Auto Parts measures out to .665-.670. One listing I ran across had the .680 dia. listed for the rear with 11" drums, but Mopar being frugal I can't see that.
I really don't want to lay the car up by pushing out studs to measure them but it might come to that.
I bought what Advance listed has the rear axle stud, the front drum brake stud (.625) and the front disk brake stud (.615) by my measuring.
Anybody know if knurl diameter is the measured the same as pitch diameter?
