A:Answer Hello Bob, the O.E.M. Radio size in your truck is a 1.5 D.I.N. size, and the PD-623B in this add is a full Double D.I.N. size radio.
It would take considerable custom reconstruction of your dashboard to get this radio into your dashboard.
You might want to look at the PDN-721HB that is a single D.I.N. size radio, with a motorized double D.I.J.N. screen that is deployed from the radio, and a simple dash installation kit and some wiring adapters is most likely all that's needed to install this unit.
