RE: canopy latch
I used the Bob Knoll method which utilizes a single MK magic box. A little tricky to get aligned just right, but it can be done. One thing to note about the magic box...the pin must be inserted into the box in a near vertical fashion. This comes into play if using pins at one end of the canopy (pivot type action of the canopy). With no pins, I added a piece of a/c ply near the top rear of the canopy to resist side to side motion. It also helps if the magic box is actuated under slight pressure, so it will not rattle.....so far, some foam tape is doing the job nicely.
