I have 2 Miller CST 280 welders. These sell for $2700 at national welders. I will sell both for $3000 or trade for a rock bouncer chassis of equal value. I have a 6.0 LS motor so I would like a chassis that's conducive to this motor. If no takers I'm just going to build one. Was looking to shave some time off the build. Located in South Carolina will deliver when I pick up chassis.
