Hi Bernard, plans are not to have any front body work, it's just a personal choice thing. For the styrene I used on the chassis here are the details remembering this model is in 1/16 scale
Roll bar tubing was 213 Evergreen rod
Main chassis tubing was 212 Evergreen rod
Chassis minor tubing was 222 Evergreen rod
Hope this helps
Hi Joe, this is 1/16 scale
