Measured 32" from seam and cut front to back ,removed the roof mounts and set back on got where I wanted it and drew a line at the overlap, ended up 3 3/4" at front and 3.5 at rear ,removed that strip from section I cut off and welded back on
Still need to cut down the roof mounts and weld back on then we do the other side
I left what should be a 1/2" overhang at the doors as a drip edge
