John Green, Probe engineering Wynnum, Brisbane, he gets them X-rayed at Industustrial imaging, Hemmant just up the road. John's drag links only work if you mount the XF box where he does which is further back than standard. John has the design and jigs for the links for each model car, he cuts, bends, tacks, but he has another guy weld them fully, up the North coast, some guy that makes Sprint cars, I think I've met him. The Xray is the expensive part. You can just cut the extra lenght from the centre of an XY link, and mount the idler and box in mirror spots, but you can get the bump steer better than that with John's design. The XY link is about 23mm different, and the differance is in the ends not the middle but the tie rods will take up the difffernace, shape is the same a 67/68. John's are quite different in shape, firstly due the box postion and secondly so the the factory bump steer is at a minimum. If you cut them in the middle it's cheaper because there is only one xray. John's need 2 one at each end.
