Thanks to everyone who answered my question about the rectangular flasher. Apparently, I'm the last one in the club to realize that the round flasher will fit in the square hole. Didn't they try to teach us, when we were very young, that the round peg doesn't fit in the square hole. Well, that goes to show I must have been the only one listening that day. Thanks for all your responses. Zak [Non-text portions of this message have been removed]
