I'm kinda glad you brought this back up. I went to O'Reilleys to get mine, but they did not stock them, and the kid could not research a sub properly, so I need to get back on this one. I asked the same question a month or so ago, and used search, but got different answers, some of which, truth be told, some of the parts needed to be modified. So, Reckless from out of Georgia came up with this answer to your question;
"ANCO 41-01 arms on my deuce and the 31-31 blades. got the arms from rock auto or ebay and went to walmart and got my blades "
