Thanks to everyone who responded, I got excellent answers to both questions. I now understand about the terminals on the lightEning protectors, and I also found what from multiple reports is the best source for fiberglass rod, and is also cheaper than McMaster-Carr. http://www.mgs4u.com/fiberg.htm Now can someone tell me where I can get a 5/8" chassis punch cheaper than at McMaster-Carr?
