Crutchfield should be able to help you with an adpater that lets you connect an aftermarket head unit to a Bose audio system. They'll probably also have a DIN adapter kit, as well. And while you're at it, they'll probably be able to get you a master sheet that shows you how to safely dismantle the dash on the vette.
Check the FAQ forum of this BBS for the "what are the most common installation problems" thread for more details on installation.
Make sure you've got your digital camera ready, we want to see photos of the installation when you're done with it. We love install porn here on the BBS.
And congratulations on your new toy!
