A good detailed blow up of Roof's racing chassis which is 90". It has the Laurel lowering brackets on the front and rear. The metal on top of the frame goes in to meet the narrow body.

Roof was always thinking. His engines were set up with a sub oil pan and he put a tray above it with holes drilled in it for the oil to drain into it. This is what is today called a windage tray. It keeps excess oil from traveling around with the lower end assembly which causes a horsepower loss.
