Think the old standard for a box section rod chassis used to be 4" x 2" x 14swg up to 10swg depending on weight and horsepower etc.
Think this build is going to need IVA. Something that Vegas Rat Rods (and other TV shows) never have to worry about.
Exactly..like I said a quick message to kev will put you right ?
Yup 2x4 is what i was thinking did get prise for 3 difrent thikness yesterday 3 4 5 mm but as monky mankys says he has 3 and 4mm is just a few notes more ill get that as it will be stronger . Cant hurt im saving waight elsewhere on the build. Thanks guys .. that one sorted
