We made adjustable stations for the six critical pick-up points on the undercarriage. We used 2x2-inch square tubing for the outer tubes and made a sliding inside tube made of 1.5x1.5-inch tubing. We cut 3 inches off the outer tubes, welded the 3-inch drop to the inner tube, and slid the two parts together. We had to add a piece of 1⁄8x1-inch flat bar as a shim to keep the tubes snug so they would still slide and be adjustable. We then drilled through the inner and outer tube with the tubes compressed together; this would be our stock floor height setting. We then drilled another hole in the inner tube 1.5 inches below the first hole so the tube would have a stock floor height pin location, and then could be raised and pinned 1.5 inches higher. This will allow us to build the jig to the car, trim out all the original undercarriage, and raise all the pickup points equally at once.
