Scotty T; Check the pics I posted under "suspension pics" . I forgot to post them in this thread. Top to bottom, end to end, side to side I measured my 99 TJ and made sketches, and checked with the dealer parts dept. for available brackets for the frame and axles. I used, for the rear, the frame brackets for both top and bottom control arms, and the spring top pad and bump stop.. The TJ has the arms at a low angle to horizontal, so I used plates butted up to the factory spring perch (see photo). I also used a factory sway bar and tied the top of it to the plate as well. For the rear axle brackets, Rubicon Express makes a kit. But more practical than that is that axles are available from several companies , even Dana 60's, with the brackets already on them. They run about $2400.00. At the time I built my wagon I bought bare axles with disc brakes and tacked the brackets in place matching the TJ measurements. I hired a professional welder for about 7 hours and he welded all the frame and axle brackets.
The control arms, sway bar links, springs, rear track bar and relocation bracket are from a Skyjacker 4" TJ lift kit. I included a pic of the front as well. The only frame brackets not sold as a separate part is the top front spring mount. I used square tube to make bolt on brackets so I could adjust them up/down to correct the ride height after const. was completed. No adjustments made so far. Power steering is a GM box with a cut out of the frame for steering shaft clearance, boxed with a section of 4x4 steel tube. There are several articles on some of the older Willys sites showing how to do the steering conversion. With the lift kit, you will need a drop pitman arm, 4-6 inch drop.
