I didn't end up having to do any gluing when I did the mod. My bulbs stayed in sockets just fine so no gluing was necessary there. And I didn't have to glue to the sockets into the housing because I drilled out the hole with a 1" drill bit and slowly filed the opening larger to the point that the socket fit into the hole very tightly and securely. It was a slow process, but at least now I can get to it to change bulbs in the future.
