We built in some extra adjustment in the windshield rake. You can match both the street angle and the configuration that the cars were raced with. (Rumor has it that the cars started the race with the taller windshield, but somehow accidentally, the windshields came loose and tilted further back. Tough luck!)
I think that those tires are Vintage Goodyear Blue Streaks, probably in 6.00-15 and 7.00-15 sizes.
