It seems that all the guide blocks I have found in the forum are at the bottom of the canopy bow and "help" the latch into its recepticle. The problem I have is that when lowering the canopy from one side, with the amount of twist present, the aft corner of the plexi (on the opposite side) hits the canopy bow well before it reaches the point where the blocks are installed. Is this normal, and has anyone come up with a guide system higher up on the canopy bow? Thanks.
