I have a 66 8 track and correct pair of stereo doors too!
I have an original 66 AM 8 track that was certified,gone through,with receipt from an electronic shop about 5 years ago. A new drive belt was also installed for the tapedeck part. I never did install the radio in a car. I stripped the flat black finish off of the front piece. Really nice shape. Paint the flat black...plug 'er in!
I also have a correct set of 66 doors with the original speakers and grilles for this matching radio. They still have the coupe glass in them. They are not rotted.
The complete set of doors and radio deal will not be broken up(unless a ridiculous offer is made!)
The doors are NOT rotted. Nice lower inner lips too. The whole set will not be cheap. Over a grand for sure.
If I sold the set from here,I'd be glad to donate to this site.
