You need to order up an ORD frame repair kit if you haven't done it yet. Previous owner had someone repair the frame on mine at one time and it was cracking again. From the ROs I found in the glove box it was less than a year before I found it cracking on me. And it sat from Dec 08 to July 09 before I picked it up and had it on the road again.
..I tend to think its the batch of steel they used to build them myself..some of it must have been recycled poor quality stuff to begin with?..
