Welcome to the forum,
This forum is full of great looking trucks; packed with great mod ideas and there are loads of knowledgeable and experienced people here.
The Cabin Air Filter Mod does not apply to 07 Rams. It's only for the 09+ 1500's, and the 10+ 25/3500's. Sorry to bear bad news....
AND - We all like pix! Got any to share?
Enjoy the Z!
