I feel your pain! I have been driving without front carpet for some time because I have not been able to eliminate all the leaks yet and I don't want to ruin more carpet and rust out the floor boards. There is a book out about dealing with this called "Corvette water leak and wind noise solutions" by Michael J Davis (try
www.fetchbook.info for best price). Here is the skinny on it: 1) Be sure your weatherstripping is in good condition, 2) Properly adjust your doors, windows and t-tops (see factory service manual or find a competent shop, good luck with this one:eyerole ). 3) Use a hose trickling water on various areas (windshield is a good place to start) to find specific leaks. I have found holes in the windshield wiper area where the factory putty seal had failed. This fixed part of the problem, but as I said, I have not been able to get the car completely dry yet. Good Luck, Cris
