I will be working on these upgrades to my Cuda as well in the near future. I ordered my boxes <a href="from http://sheetmetalstuff.com/" target="_blank">fromhttp://sheetmetalstuff.com/</a> they are thicker and tiq welded. I got my frame connectors from http://www.magnumforceracing.com/store/d...arch=&Page= They can be bolted or welded in, I plan to do both (bolt them in first and then weld them. I plan on putting the frame conectors in first and then the boxes.
