Chris, Did you mean "tired of banging my long legs on the dining table." leg? Or did you mean you want the table mounted higher?
Terry M. has a great tip for you about calling Scott. Scott may also several as I know some other Alpines have removed their table. Basil I think was one of them with his Apex.
I'm sure Dale Gerstel or eMike could help you out with photos and measurements when they see your post. You might also want to look at a post by Dale about his table. It shows the bottom of the table, but not the bracket.
My Alpine has the wall mount with a single leg on the other end. I might want to do a legless install my self. Would be interested in what you come up with.
By the way, my wife still to this day liked our all wood floor mounted table in our 2001 Alpine the best.
