This is the model intended for a 2dr JK with the back seat installed, but can be used in either model with or without seats if you just need a secure storage area. When the tailgate is closed, this makes a safe spot to store stuff with the top off. Selling it because I want to install the 4dr model (my back seat is in the garage!).
For stock photos and info... http://www.quadratec.com/products/14036_001X_PG.htm I think this is missing a section of rubber edging trim, but I'm not sure. Retails for $197, asking $125.
