Thank you so much for all the information Dave! Appreciate your time in writing this out for me. This is my first attempt and this forum is perfect for finding the answers needed. Andy

I have an original 1957 Chevrolet 2 dr. hard top BelAir 2400 Series vin#VC-57L191778, My questions are: What tires are acceptable for judging? I have four (plus spare) Bias ply, original style white wall tires on vehicle. Can I replace these with Coker Radials and not lose points? Are rear fender skirts acceptable, if original replacements for judging vehicle? The car has spinner hub caps, which I believe were an option for this vehicle. Are they acceptable for judging vehicle? Do spark plugs have to be of correct brand name for that year? If not what is acceptable for judging? Thank you for your help.
