I realize that the dimension between the attachment plates on the wings and the bracket on the cabin were not exactly the same. I have a difference of 3mm. Since those parts are rigid and can't be bent, I had to move one of the wings attachment to match the cabin. After talking with the expert at Bushcaddy, they told me to move the rear spar attachment and leave the front one as it is, so I've made spacers and reassembled and torqued everything to spec.
