After you do initial fitting and drilling, you need to spot prime and rivet the structure of the frame together. I deburred, countersunk and riveted the two frame halves and the angles that support the goose-necks. Next step is the big one.. I need to drill the goose-necks. I will need to make sure this thing is fitted and as solid as possible before doing that. I do think I am going to go forward with the mod outlined "here". This will ensure that the canopy frame is not pushed forward once the spring loaded struts are installed. They tend to move the frame around a bit which might mess things up down the road..
