1974 newport

I want to upgrade the stereo in my '74 Town & Country. Wally World sells a Scosche brand adapter that states that it works with Chrysler products back to the mid-1970's, but we all know how products don't always work or fit as the packaging claims. So I figured it'd be better to ask here first...
