Thanks, Don. I will probably have to cut the body off to do that since the rail at the firewall is higher on one side than the other. Also, the rails behind the body seem to be ok. From that, I am assuming that the problem is under the body. Also, I didn't tell you that the previous owner welded a 1/4 inch steel floor to the body and frame. Maybe that is where the problem lies. I will let you know...Thanks again
