I used 2 x 2 x 1/16 wall steel tubing myself. The only thing I might have done differently is cut the gas bar shorter and tig weld cover plates on the ends of it to bring the OAL to Lonnies specs. Then weld the assy to the Brutus frame. This would insure an easier leak proof seal of the gas bar assy. If you over penetrate during Mig welding in the corner of the gas beam you've got problems with out having covers sealing the gas bar....YMMV good luck...
