No problem. And if they don't work they still have value as guys are gutting them out and filling them with modern cd player stereo's and they make it so the entire front of the 8 track case just flips down with the radio hidden inside. So if one is beyond repair it could still be a donor to someone. Also there is some kind of bracket that I think might be hard to find but can probably be made? I have service manuals I can look in if this becomes a crisis for you, I would assume its just a couple wires and a couple bolts and bracket.
My brother was the top mechanic for a Buick dealership for many years. He always said his most important tool was a ball peen hammer . Lol . Good luck in your search. I bought a couple of Ebay in the past.
Thanks Jim for the response. I purchased one yesterday here on the board, but I will keep your information should I need another for parts. Thanks for the pictures and your effort. Jim
