Hi Guys!,
Just checking in and saw some activity here. I don't miss the leaks!
I would definitely take the old fabric off to check the hinge condition and to clean and lube it..paint it if it's rusty before putting the new fabric back on. Buy some heavy duty waterproof canvas and butyl tape to seal the moldings back on. Also important are the screws, if the old ones are rusted chances are water will leak past them and in. The tilt out window will probably need to be resealed. I removed the whole assy and swapped the glass with smoke lexan. It made the window lighter and leak free once it was siliconed in place. Some new foam weather stripping around perimeter of frame will seal tight when you lock it closed.
Hope this helps get your leaks fixed.
P.S. still have mine....maybe subliminally I don't want to let it go..
Don't tell wife. :)
Take care.
