I'm in the same boat as OP, but I don't have a radio in mine at all. I've bought quite a bit of stuff from Crutchfield, but I'm seriously considering finding a stock radio. Why? 2 reasons.
1. The stock one isn't as likely to be stolen (hopefully)
2. Stock radios have large, simple to use controls that are very hard to find on an aftermarket stereo.
I'll probably visit local salvage yards when I get ready for one. Chrysler used the same radio for Jeep, Durango and Caravan. As long as it's the correct one, it will fit right in.
