I have a fly 911 Rally with the navigator head bashed in and BFGoodrich Canada decals for Ludwig Heimrath IMSA. Has the little duck tail. I have the original narrow wheels and tires that would put it in rally track shape. I also have the low end motor, but also the Olifer chassis to make it a big track car. I strongly advise that the rules spec a tire and wheel combination that is narrower than our Targa Porsches. The motor size also appeals to me, but allow any 12k motor like a Scalextric would have as a white end bell. I have wanted a small Austin Mini Cooper from Scalextric and would need narrow tires. The 904 and 914 (I almost bought my neighbor’s in 1973) are enticing. I keep wishing the rally rules allowed multi-car teams because I want those cars. For information use, are there some appropriate bodies for scratch building with a Penelope Pitlane or Policar F1 chassis, like an old Saab?
