Steve , I have a new knock down chassis here that may suit you . This is a big boy kit from Bugpack and is the wider 60" model . I have the complete chassis that has 2 welded sides and a box of cross braces that need to be welded in place to complete the chassis .This is a K&L front and IRS rear deal with a new custom torsion housing if you want this . I also have some 3 x 3 rear arms , and some 4 x 2 front arms with combo spindles as well . This is a 2 seater wide chassis kit that is made of 1 1/2" x .095 wall mild steel tubing and it has been here for 6 months , $ 1000 , ROD , 02-42729920 .
