I snagged one of these in case someone with an 04 or later wants to do the cabin air filter mod.
Price: $12.00 shipped via USPS anywhere in the 48 states
Condition: Used
Payment: PayPal only
Returns: Sold as is, no returns
About the mod - 02 and 03 GMT360/370s came with a cabin air filter door but no cabin air filters. Some of us 02/03 owners installed cabin air filters. In the 04 and later models, there is no cabin air filter door. Some 04 and up owners cut a hole in their HVAC case and added this door as well as the cabin air filters. In my 03, the filters did not reduce the output of the HVAC blower.

The price is firm. This isn't pawn stars so don't bother lowballing.
