Looks beautiful. I have the kit and never was brave enough to build it. Btw Porsche ran Indy cars in 88-90. Teo Fabi was the main driver with John Andretti teaming with him in 90. They won one race in 89 and had a very good season. Keep up the good work.
You know to get more accurate wheels like that came standard on the 80 Roadrunner you could use the wheels off of the AMT Ford Courier step side pickup. The wheels that were standard that year had color inserts the same as the Road Runner decals. So with the new decal sheet you would probably want to use red as an offset color.
