Well, maybe late to the party, but i'm currently doing these - more or less that is...
I have a set @ printers which should become available in 3-4 weeks. I did not copy the existing sheet, but started from scratch as the original shapes/sizes were way off. My set will not include any of the red areas that will need to be painted, and the new set depicts the LM 1974 racer which means it has a lot of additional logos compared to the original set but is also lacking the brands hatch specific ones that were included previously.
