Update on my mod. After having it installed for a couple of months found that I was getting alot of noise from the airdam above 60mph due to the loss of reinforcement ribbing on the back of the plastic, even with the metal rod installed in the rubber strp, (00-01s only). Thought I saw somewhere where someone had installed some weather stripping along the roof so I went to Home Depot, got 5/8th thick x 3/4 wide weather stripping and installed it along the roof where the dam meets the roof. Stopped all the noise even up to 80mph now. Probably would work on all 00-01s.
