I have an Eclipse 5504 CD head unit with built in EQ I would like to sell. It came out of my '98 Chevy Dually and is a nice little unit. I swapped all the equipment from my former truck into the dually so have no need for this unit. It is a DIN and a half and I know will fit 96-99 Chevy full size trucks, suburban, Tahoe. Looking for $100 and you pay the shipping. I can e-mail pics to those interested. Im located in Fullerton, CA.
