[1320racer]

there are few sportsman racers without the benefit of a full time team/employees that have as good no mind a better preventive maintenance program for their cars than I. My cars show it in their performance, appearance and most important wins!

That said the OP has a door car, not an open cockpit car and if he races in a dust bowl his preventative maintenance should start with the carb, not a component in the interior of the car but hey, some like to make it more difficult than it needs to be.
