Re: body cracks at seat mounts
I hadthesameproblem, I took two pieces of 4"x4", 3/8's inch metal, drilled holes in the four corners and another in the middle, I used theseto sandwich the broken metal, and bolted the seat through them. I then usedsome rtv to seal around themetal to keepthe rust level down.It has worked great for me for a year now. I weigh over 200lbs and bounce pretty hard out here on the sand, it has held up just fine.
Hope this helps,
