These skymaster cockpits are great, I really like the seat detail and the atmosphere both create once installed. My only problem with them is the material used is so brittle that they are nearly always damaged and this one was no exception. The best way to strengthen them is to glue 1/32nd ply under the lip and then make a fillet of epoxy around the edge. After this they're strong enough to mount directly using the cockpit flanges.. Both cockpits will be mounted inside the canopy making access to the equipment trays easy. I repaired the damage which involved some filling, sanding and a re-spray then painted the inside of the canopy frame a matching gray. It's very difficult to bond anything to the plastic SM use. You only have to look at the seats and they fall out. The best stuff to glue them back with is UniBond clear sealant.
The cockpits are then secured inside the canopy frame with tiny countersunk self tappers.
