I am also interested in getting the Mustang classified in prod. Although I would prefer it to be in E prod as full prep (as a Pinto replacement), getting into F prod (with no more restrictions than the Volvo) is at least a start. I have already talked to Brian Culbertson (at the Runoffs, as well as other occasions) about the process. A letter-writing campaign definitely helps, as it shows interest. What details did you include in your letter? BTW, the Volvo 142 in E prod has lost over 200 lbs since 1999 (last GCR I had handy) - 2260 lbs then, 2050 lbs now. Someone is being vocal to make that happen - but have you seen one??? They are even losing interest in ITB (at least around here).
