Just started a new 240 project and im installing a fuel cell, there is a little rot in the rear where the muffler hangs. I want to remove the trunk metal fix up the frame and fab up some mounts in between the rails for the tank to sit on. then ill replace it with some flat sheet metal. Can anyone give me some tips on removing the trunk floor? Where the welds are, where to cut, where to drill, i do all my own work and am very able. just looking for some one to point me in the right direction.
