Ive read several threads on this problem but the TSB seems to be on 2004-2006 trucks only. Just wondering if the TSB elbow is the same for a 2007 truck. Most forums show the Ac drain tube on the firewall..mine has a fiber board heat shield that looks like its molded to go around the drain and it is not exposed as described in the TSB for 2004-2006 trucks. Suggestion?

Thank you!
