I really like the mod, but are you going to make sure every number is done for every car? I've only seen numbers 1-30 done for most of the cars, with a few exceptions (the McLaren Mercedes only has 1, 44, and 77, which is a bit of a shame because those numbers look nice with the red stars on them). Part of the reason I ask is that it's a bit annoying to see some drivers appear to not have a number at all (particularly F2 drivers that get promoted).
Also, I think the Ford has the stamp for #23 loaded over #22.
