Peterbilt 379 Unibuilt cab kit. Kit includes headliner, radio piece, 2 door panels, and 2 cab corner pieces. Our standard kits come as a three piece headliner. Also included are 2 aluminum side pieces to install above the doors behind the headliner. These are so you have something stronger to screw the headliner to on the top sides to prevent it sagging over time. It also provides something to mount speakers to so they don't come loose and fall out over time.
 
Fits 379 Ultra Cab (not flat top) year 1995-2005.
