John Green at Probe Eng does the cutting, and has a jig for each model, but he has an expert Race car welding/building dude do the welding so they don't fail the xray, he does them with a mig but uses different wire and different gas. John does other steering type mods for people building buses, motor homes etc. He normally getts them ready and then this bloke comes down from the North coast for a day, welds them and goes home. John's designs only work if you mount the idler and the box where He does. He does the links for one of the mobs on the Goldcoast that conver stuff as well. Peter Menzies will have stock Falcon links, you can cut up an XA as well. Your 66 will be different to my 67 link as the link is at a different height. John can do modded Falcon stub axles as well to fit Falcon Discs I think to pre 67 cars so the bump steer is ok.
