Remoted the HAM speaker to the front dash. Look ma no wires!
This is the Midland 21-406 and it fits. You will need a small rat tail file to elongate the holes a tiny bit and the wires need to be orientated up as the opening is slightly offset with a larger gap at the top.
It is made in China but I bought mine from Camelot on their last day before closing down so I guess that is a wash.
