Found elev skin to be bent out of square along trailing edge. Skin was good on right side,but some 4 mm. out on left side. This makes skin long by 4mm. on top left and.short by 4mm on bottom left. This gives an 8mm overhang to skin on left end as shown pics 2&3. Will send an e-mail to Zenith with pics and talk to someone tommorow.
