I went ahead and drilled a couple small holes in the tunnel and ran a zip tie underneath I got a hold of some silicone strips about 1/16 thick by 1 " wide I will have a friend RTV to the underside of the tunnel for the can to rest against. I can slide another piece under the zip tie where it comes in contact with the can. this will allow me to take the can out if need be without having someone spread the RTV a second time. I picked up some batteries for my camera today and I will post some pictures later.

Getting really close to maiden now just a few more odds and ends to go
