I cleaned the inboard rib, BNC connector, and vent fitting with MEK and then mixed up a small batch of Proseal and sealed the two fittings to the rib. I also called Van's today about the 2 missing spacers. They said they would FedEx them to me, no charge. What a great company!!! I should have them by Friday and still be able to still head up to NY to finish this sucker up. Can't wait!
