Turning back the clock
in the early days of Pro Stock (70-75).... Ron Butler was THE innovator, and IMO, his cars were the class of the field.
Know where and who actually built the 72 (later updated to a 73 ) Mopar Missile? (hint) it wasn't in Motown. After the 72 Missile Butler built Butchs 73 Pro Stock Duster, the first Mopar Pro Stock race car featuring a complete tubular chassis with rack and pinion, and yes, headbanger bars, same with Bagshaw's race cars. Of course it would make sense....Ron Butler was Bill Bagshaws neighbor.
Butch didn't mind the bars...he needed a place to rest his arm as he literally steered with 2 fingers.....at 150 mph!
