We designed some very simple .090" bumper mounting brackets on 3929 based off of 2826's. They have simple 90* bends to form two tabs on the sides to rivet or bolt through. https://sphotos-b.xx.fbcdn.net/hphot...81089086_n.jpg

That drive also used 2x1 tubing and had 0 issues with the chassis as far as I know. Bellypan was integrated .090" pan into the front and back cross member. 10/10 would build again.

Overall, I must admit I enjoyed designing with 2x1 tube much more than with a pure sheetmetal frame. I felt that it simplified the design and was easier to have parts manufactured with a mix of tube+sheet.
