Ok, with that plane the conversion should be easy, because the windshield goes up over the front of the wing. But the first thing you must check, is that there is a PLYWOOD former in the fuse forward of the Leading Edge of the wing. If there is not, you will have to add one, and it must be deep enough into the fuse that it will lift the entire fuse (Including G-Forces). Next you will have to epoxy two plywood blocks (About 3/8" thick) to the fuse sides and the Fuse Former at the rear of the radio compartment (A). (Some square or tri balsa stock under these is a good idea too)

You will also want to remove a little covering from the center of the Trailing Edge and glue a piece of 1/8" plywood as wide as the Fuse to strengthen it for the bolts (So they won't pull through the wing during a loop!)

Now put the wing in place and rubberband it down so it won't move. And drill two 1/4" holes STRAIGHT through the windshield (and plywood fuse bulkhead)-into the LE- and through the wing joiner. Next, drill 2 holes through the trailing edge and block "A" (Your choice as to what size depending on if you want to use 1/4" nylon bolts, or steel bolts with blind nuts). If you're planning to use 1/4-20 Nylon bolts, drill these holes 13/64", then tap block "A" with 1/4-20 threads, and after the wing has been removed, re-drill the wing holes to 1/4".

You can then add two 1/4" dowels to the holes in the LE. Make sure they go all the way into the wing joiner. And if the wing insn't fiberglassed in the center section, It would be a good idea to do that (Lest the dowels pull through the LE)
