For the canopy, I used a cabinet door latch from lowes. .89 cents. The kind with rollers and metal tang. I glued some square hard wood across the rear of the canopy opening inline with the canopy screw holes.. ( don't go all the way across unless you plan to remome the screw tabs from the canopy) leave room for the canopy tabs. i glued it to the plywood brace that goes across there. I did the same to the canopy, where i mounted the metal tang. Not sure how to upload my phots' of this to you. it won't let me browse for the photo. anyway this has worked well for me.
