Description
ATRO HM75-64001 hood pivot bushing kit for Peterbilt 357, 378, and 379 conventional cabs. Replaces the Peterbilt OE bushing (13-04726), sleeve (13-04727), and hardware kit (23-15273) at both hood-mount pivot points — restores tight hood pivot, eliminates fore/aft slop and the metal-on-metal squeak that develops when the OE rubber bushings deteriorate.
