Got some body damage due to a brake booster failure at Apple valley Farms in Chetek WI this past weekend......








So, my plan is to shed some sheet metal. I'd like to take the box off and build a cage to house my fuel cell, radiator and a toolbox. the plan then, is to build a cage around the cab, and I'm thinking that dove-tailing the front end and extending the cage foreward from the cab to a push bar. I've seen lots of rigs like this and think it would be really cool.

So, questions:

What is the ideal size tubing for this type of work?

Where in minnesota (MC's neck of the world) do I go to buy the steel supplies I need?
