I built mine using two engine stands. I cut the vertical part of the stands and re-attached them so that they were straight up, instead of at a backwards angle. I also made brackets out of larger square stock so that the crossarms are adjustable. I will try to post some pics later today after work. I also cut the vertical section to put a "riser" inside so that I could raise and lower the car using a hydraulic ram on both stands. Worked well for me.
