I'm sure our head judge Gil Cunninham can clear this up better, but from what I understand, any type of equipment that the car DID NOT come with when it was built will have points deducted of in concours judging. The people who volunteer to have their cars judged this way should be prepared to have points deducted for non-stock items. This would include disc brake conversions, tires, seat belts (I'm really not sure how the club has been treating this one), engine swaps, electronic ignition, color changes, and on and on. This has been argued over extensively in the past and there is no point in starting it up again. If you want to modify your car and drive it the way it was meant, enter it in peoples choice. Concours is for factory correct cars, that are usually not driven extensively. 300ly, Don in RI ----- Original Message ----- Would such an effort cost points in a judged meet or would it be treated as a safety(environment??) upgrade as tires or seat belts are? Speaking of this, how are disc brake conversions treated in judging? Roger Schaaf 300 B Calif
