Here is the link: :http://www.throttledownkustoms.com/Jeep_Frames/jeepframespage.htm They have a standard frame rails on this page for $575.00 plus shipping to your location. This is how I kept the frame level and square, I had two metal saw horses that I leveled up in the garage, laid the outside rails on it, and then I used to pieces of 2x4 boxed tubing laid on top of the rails and loosely clamped them. Then I squared up the rails and crossed measured them to make sure they were parallel to each other. Then I tighted up the clamps and re-measured it, then I made the rear cross member and tack welded it on, re-checked measurement again. Then I made next two cross members just like a jeep frame in the same location, and tack-welded them in, again I re-measured, checked for square ness, so what I’m saying is that every time I tack-welded something in I made sure everything was square and level, and used the back bumper as my base line. Then when everything was good I started welding them in solid. At this point the frame was solid, so I flipped it over and started putting in the spring hangers again making sure the hangers where square with the frame. The key is working slowly and keep measuring to make sure everything is square. And, the guys that I got the frame from gave me tons of advice on the phone anytime I had a question, hope this helps you fellows go and build your own frame.
