I read it but unfortunatly the two pics at the top would not open for me and the words much shorter mean alot of diffrent things to diffrent people. Would it have to be mic'd or would you be able to see the diffrence with a tape measure and is that outside to outside or is there a diffrent piont they are getting that from. Sorry for the questions but I am over in Italy and don't want to be pulling this thing out in my driveway again to replace it.
