I have a broken stock tape/radio unit on my -00 electra. It seems to be real hard to find a replacement with a CD player that fits my -00. I do not want to put in the sony marine, just dont like the looks... I have found several HARLEY DAVIDSON HARMON KARDON RADIO PART #76160-06 available on ebay, but they are for newer models only. Is there anyway that I can modify my -00 to fit the Harmon Kardon unit?
