It might be time to start letting your fingers do the walking, then. I would think that the tech support areas for any manufacturer could give you the dimensions you need. I just hope you get better response than I did from King Kutter, who told me "Our attachments are NOT quick attach compatible at this point. Maybe next year." They're not even cosistent from one attachment to the next. AMAZING! /forums/images/graemlins/shocked.gif
