Cipa Mirror to trade

I have one of the new Cipa Mirrors that has adifferent mount than the old ones. The old ones mounted to the straight bar and thus can mount on a tower mirror mount. Mine has a different mount that has a ball type mount on the back and I cannot take the mirror off and put it on the tower arm I can only mount to the windshield. I am looking to trade for the older type that nounts to the shaft. If anytone is interested in trading, send me an e-mail Thanks kjames@csus.edu
