I would like to have a sketch of the crossbar and the plates. I have access to a cnc plasma cutter and aluminum and stainless steel metal and would like to see if I can duplicate them. If so I think I could save our J-30 owners some money on these kits. Seems like $400 is alfully hihg for what ive seen on the phioto of these items. If you are willing to send me a scetch of these items let me know.
