These are the files to print the conversion kit shown in the last 3 picture in 1/32 scale. They were designed to receive standard in line Slotit motor pods, Scalextric C8071 guide, Scalextric contacts W8658 and fit in the Airfix or Revell 1/32 VW Beetle model kits. You can use your choice of wheels and tyres but if you want the same as mine in the pictures please get in touch.
