The first prepunched empennages...
came out in January/February, 1996. When I placed my order in January, someone in Van's office told me of this new product. I received my tail kit at the end of Feb, 1996, and the skins only were prepunched. I don't believe that the ribs/spars were ever prepunched. I received my wing kit in December, 1996, and again, the skins only were prepunched.
