Will my forum bindings fit on my burton snowboard?

i bought the 2009 forum arena bindings but i have a burton snowboard. i cant seem to figure out how to get the holes to mach up. because the burton boards use the 3 hole mounting system thing not 4 like every other board. if you can give me some advice to make them fit i would really appreciate it. thank you|||You need the adapter, available at any shop that sells Burton gear, and even some shops that don't sell Burton gear. Call around and ask, they'll know what you're talking about.
