Thanks for the response. Yes, I'd be interested in getting the long 4" test plug - we only need one. I'm in NC and would gladly pay the shipping and compensate you for your trouble. How long ago did you use your plugs? Some of these plugs are quite expensive to buy and I hate to spend the money for a one time use. On another board someone suggested that I needed a 20" long version and it was over $200. That's one of the major problems with trying to do construction yourself.
