No, I don't know for certain if that jack will fit the board or the panel hole.
They are also on eBay.
If the jack on the radio is damaged I would certainly consider replacing it with something different. The trouble is these coaxial power connectors have their voltage and current specifications and some are not rated for this use. That being said, most any of the larger sizes would probably work just fine as they can handle far more voltage and a little more current than what they are rated for for intended uses.
