Revamped the center spar by putting in a support beam so I could pull the back end down and git the center spar with a more approximate curve to it.
Here's what the back end looks like now...I still have to reshape the rear window fer my upcoming trip to Tampa, FL...
Slid in a section of aluminum flashing in place of the Coroplast ducktail...
Got some rain to test it with...you can tell I need to use an English wheel to reshape the back part of it...
