That print leaves a lot of numbers out. You can't build an accurate car from the information there. I've been lucky enough that I have verified alot of information and measurements off real ones. Main frame tubes were 4" dia 0.095" wall originally, the new version use .120" wall for a lot less frame flex. The 3/4" square and round tubes that make up the birdcage etc are mostly around .055 to .062 wall.
