I have a couple of 91 Cassette Player, no equalizer, stock radios. Both of them work, but have a bad output section, ie one or more channels are dead. For some reason this was common for the 91 units. If you need the stock mounting brackets, I'll have to look, but I think I have extras. Same with the electrical connectors.
If you can come by the house and pick it up, all I want for it is you buy lunch. If I have to pack it and ship it, you're still buying lunch, plus USPS. So I'm thinking $30. Let me know.
