Even some of the experienced people (shops) have no idea as to what board goes in what, I spoke with a reputable shop and was told to purchase the Tsunami TSU-GN1000 and nothing jived when I removed the body or should I say did not look proper. I then called Digi and was told I needed the AT1000 great now I have a board I cannot use. Darn this stuff is like a crap shoot. 7-11
