Paul,
You don't need to buy anything. Notch the deck rails about 11 1/2 inches aft of the roll bar, and notch the guide rail where the slider block winds up so it can be lifted free. Install a drawer pull (handle) on the aft end of the center canopy bow as a grip. Use a piece of 3/16" piano wire as a support strut between the canopy and a hole drilled into the pin block. To lift off the canopy, pop out the two bolts joining forward canopy bow and the rollers and hoist it away. (You don't need nuts on these bolts for flight. Impossible for them to move forward.)
It's a really useful mod. Makes baggage access trivial compared to no tip/remove.
