Before I broke the stock radio and pulled it out, I had it sitting under my aftermarket as a dummy...or to cover the hole. They both filled the radio cavity perfectly. I broke it and pulled it out so now I have the big hole under my aftermarket.
Im pretty sure the stock radio/tape player was a 1.5 din and the OEM CD player that accompanied it was 1 din. Dont quote me on that though, I yanked it out awhile ago.
While we're on the subject, anyone know where to buy a cheap plastic pocket (for CDs and such) to put in the hole?
