Don an BiggTony,

Don I took your advice and inspected for cracks. Didn't see any but sometimes you don't see them until the screw is in, so I went and clamped the housing and put some testors all around the inside of the socket. Let that dry overnight and when I put the screw in today, it felt almost like it was having to re-thread the hole. It was very tight and I think the screw won't back out again. Thanks.

Jim
