I've been doing some research on the Uncertain T color and this is what I found.
The chassis is steel tube, painted red. The 1957 Buick nailhead, with it's block painted brown and the intricate detailing of red paint, was bored and stroked to 386 cu in (6,330 cc) and equipped with 11:1 compression Jahns pistons, Hilborn injectors, Scheiefer magneto, 1963 Buick cylinder heads, and open headers. The transmission and quick-change rear axle casing were painted brown, the rack and pinion and torsion bar tube yellow.
That is some crazy colors. Not sure if I'm going with that or not.
