Phat, I'm wondering the same thing that Air mentioned. How would you use threaded screws/bolts and nuts?

Fray, my hat's off to you buddy. Nice work so far. Thank you for posting the step by step process. As said earlier, this thread (because of your attention to detail) will prove to be very helpful to many guys down the road.

About the cross supports, what's the difference between the direct transfer of weight from the cover and the transfer of weight to the cross supports that rest on the tank? I could see a difference if the cross supports were tied into the stringers or something, but as long as they're just sitting on the tank, do they really help? Just asking...
