Thank you all for your kind words. I've been out of circulation for so long I figured I was forgotten by now!
I've been bugging GMP to do wheel and tire sets for quite a few years. I even started getting others to write in. This is a market test and if sales are good, there will be more to come. The K-H are the 5 spokes that look like double spoke Magnums. It was distinctive to a '67 Shelby. I should also point out that the GT type wheel could be done as well as the steel slotted wheel w/cap and trim rings. GMP also did '69 Cyclones and GTOs. The GTOs have a nice selection of wheels and tries. As programs evolve, new sets would be introduced. You will have to adapt them, but this bunch should be good at that. I did managed to get GMP to agree to keep the sets under $10. I'd like to see them made easily available and affordable. When I built my '70 Nova SS I used Mint type wheels and tires and that model popped. I know I can paint tire letters pretty well but I have to say the detail is pretty crisp and I wondered why I wasted all that time!
