You can drill and mount the rear wing plates whenever. The wood won't splinter as bad if you do it after you fuel proof. You can then just drop epoxy or CA on the nuts to hold them.

Same goes for the landing gear. I went to the local Ace hardware and bought some 1 1/2 wide aluminum, 1/8 thick. They bend like 99% percent of the dural gear out there. The fuse mount is 4 inches, the angled sides are 6 inches, and the axle plates are 3/4 inch. Use whatever design you want. I like using nylon bolts on the gear, as they will snap long before you break any wood.
