I saw a comment about the fuel tank drain valves being different if the bubble doors are installed. Please tell me about that. If they are different, can I specify that I want those fuel tank drain valves sent with the kit instead of the standard drains?[/QUOTE]

I have the bubble doors and the wing tank valves are not a problem. I just installed the hydraulic door lifts (those shock looking things)where the bubble doors wouldn't touch the valves. James Thomas
