Chrysler AM/FM 3501623 Radio

More Info from Wards in response to my questions...

Saturday:
I have had several of these radios in the past that have had this exact part broken . No other radio has a part even simular to it,
so it has to come from another 72-76 A body AM FM radio . The way the switch is thrown and the shape and contour of the linkage is unique to this model only.
The linkage was made of pot metal and often broke . In the past I have attempted to repair these with epoxy , jb weld etc .nothing would hold
since the part is put under stress when used. In your radio, the other half of the linkage is missing all together , a previous owner must have removed it.
I have one other am fm A body here, but I have already had to rob that linkage for another customers radio in the past.
The only thing to do is buy another am fm, if you want to put that much more money into it let me know . Your looking at approx another $ 100-$ 125
to get a non working radio for parts .

Sunday:
To switch from AM to FM you twist the RH inner knob . The shaft the inner knob rides on is all part of the one piece pot metal linkage.
That part is still on the radio , when it goes inside the radio it takes a 90 degree turn , then another 90 degree turn ,and meets up with more linkage and untimatly, the switch itsself.
The part that is broke is very intricate and not something that could easily be made or rigged together.
Because the inner knob shaft is hollowed out, notched etc and is part of the one piece linkage there is no way to fabricate anything .
If you want AM , We will have to buy another radio to get the correct linkage piece.
