I spent some time tonight doing a canopy mod that isn’t in the instructions but most people really recommend. The canopy is held in place only with the goosenecks in the front. When the pneumatic struts are installed and the canopy is closed, there is a large amount of forward pressure on the front corners of the canopy. This pressure bends the canopy frame and changes the alignment with the front skin in negative ways. These stops that I put in are adjustable and push back against the canopy frame absorbing the pressure from the struts. You can see here how they work. Pretty efficient and other than remaking the angles a few times weren’t that difficult to install.
