in the late 80s .....1980s,we pitted next to mike burt and he went out of his way to show us the way the rear axle was mounted, he made abig thing about how intricate the tubes that held the axle in were.T his is what made me think that the chassis was the iron hose car also the upright next to the motor plate was rectangular.Obviously when this car was built funny car chassis hadnt standadised yet ,so individual builders, and there were lots of them,put ther own ideas in. There is a list of sema approved builders of the era on we did it for love i think.
