Stephen, I had a quick search for the round 2 pin plugs and don't have a lot of good news.If they are the round type then you would be better off changing the socket to another type.I would be happy to do this for you but if you are in a small town or know a tv/audio repairer they would be able to do it for you.
Cheers Mark.

Thank you for the info, yes 2 small round holes in the side of the radio, one larger than the other,.. have installed the radio, so reluctant to take out, and pull the radio to pieces to change it .. I have seen some around at swap meets on early car wiring, so will keep checking and hopefully will pick one up, I .. I am not too fussed that it;s not working yet, still looks good mounted in the dash,.. just thought that someone on the Forum might have had a spare laying around .. Thank you .. Regards Stephen
