Sorry for the off-topic question, but my friend is building a 1964 Dodge Dart station wagon for drag racing. He wants to upgrade the 9" front drums to 10" front drums, either bolt pattern is fine. What must he do? I can't talk him into disc brakes. Thanks, Sean ---- Please address private mail -- mail of interest to only one person -- directly to that person.
