Another option is to get the tubes laser cut as I did. Here are some samples http://web.zone.ee/mopple/Haynes/DSC_0816.JPG, http://web.zone.ee/mopple/Haynes/DSC_0812.JPG.
Can provide DXF contours for front wishbone tubes, as my rears are a bit different from book design. BTW I have spare ERW tubes for front bones if anyone is interested.
