not really sure m8, we got a hole at the moment from piccies in the owners manual - looks similar i think
The link I posted is for a radio from a pickup but GM usually uses basically the same Delco radio across the board durring a model year except in the higher option packages and in Cadillac and Buick.
I would have to agree with F Body if you want functionality but if you're looking for an original radio to fill the hole the one I listed is a pretty good price for a guarenteed working radio. You could get one cheaper at
www.car-part.com but may have to pay more for shipping.
BTW, everyone may want to bookmark this link
