Hi & welcome to the forum,
why having sleepless nights?
there is a cutting list available somewhere, sorry but i don,t have it, tho being honest....if you bought the correct qty of steel you won,t have a problem, the steel is fairly cheap, most folk spend between £100 to £110 on the steel plus delivery.
as for CAD drawings, have a look for a thread by forum member "Fabrun" who is doing some stunning CAD drawings of the Roadster, maybe he could help you out
there is always folk willing to help on most subjects of the build, so if you get stuck then either look in the search facility for similar discussions or ask a question with a new thread,
Good luck with your build
cheers
andy
