I got the Roger Penske Sunoco Special done. Still need to add Mirrors and fix up the pin stripping a bit the photo is telling me.
I never had a proper decal set so I improvised and used some 132 scale stuff I had laying around. Call this a close facsimile
Follow up on the Lego wheels. I was able to order rims directly from the lego store. They come in 9mm OD as shown in the picture, and 11 mm. So I ordered a bunch of both. 120 rims for $20 including shipping.
I also got into tire casting mode and made a new urethane to fit these rims. I also believe my original Barc Bites will fit on the 11 mm rims nicely.
