No apparent issues turned into two issues but both are warned about in the plan.
First the aft end of the weldmount flange is pulled away slightly from the skin/longeron. Plans say if this is 1/16 or less just tighten the bolts, or bend it in otherwise. Mine is about 1/16 but it was easy to bend in slightly and you can see the better fit. The other side had less than 1/16 space and I didn't see it until after I was done, so per plan, I'm just going to tighten it. You can see a piece of .063 (about 1/16) won't go in the gap.
