Well, just about went crazy trying to figure out how to obtain adjustment to the steering box. Went out and purchased a 17mm crow foot, but no help as the crowfoot did not have the depth to reach the nut. Finally found an old 17mm open end wrench in the tool box and welded the wrench to a three eights inch extension. In essence, I just made a crow foot wrench with greater depth. I welded it about two inches behind the head of the wrench opening. It worked great to loosen and tighten the nut. Now the other problem was to adjust the allen head screw, which I could only access from under the car by removing the exhaust plate ( easy job ), and turning the steering wheel all the way to the right for arm acess to the side of the steering box. A tight fit, and use a short allen wrench. Basically you have to adjust the screw from the bottom and tighten or loosen the nut from the top, sometimes resulting in several adjustments until you get it right. But it can be done. Make sure once you set the adjustment from the bottom, you finger tighten the nut from under the car, then when you tighten from the top, you minimize movement of the screw. Hope this helps BobbyG. PS- Don't forget to hacksaw off the excessive length of the wrench after welding.
