I received my Aircraft Spruce order today with the machine screws to mount the roller latch guides to the "roll bar." We drilled the holes, countersunk the guides for the screws and mounted the guides. We reattached the canopy frame and tried it out. We spent the remainder of the evening adjusting the latches. I think the latches are good to go. I need to order some smaller muffin fans as the 80mm fans I purchased are too large to fit a RV-7 tip up.
