Did you know about Custom Autosound...?
http://www.casmfg.com/Their models have knobs that can be adjusted to fit any application for old cars and trucks.
They also have very good customer service.
A few years ago I bought one of their USA-5 with 10 cd changer new w/warranty on ebay at a great discount.
It has radio, cassette, cd and now even iPod.
2x 35W stereo, front and back.
It fits both my 3100 truck and coupe.
Used to have it in my truck and then put it in my coupe for the long freeway trips.
Got 2x 80W 4" speakers in a speaker box I made behind the stock speaker grill and 2x 130W 6x9 speakers inside speaker cabinets on my back seat.
