You're going to need the matching M5M plate.
I have a universal plate (from an older use) for my monolock box, and I bought the FZ447 arms and M5M plate over the Winter. I don't have them installed yet, so I just measured the mounting points on both plates:
The M5M plate mounts to the arms thru four set holes spaced as follows:
6.5 inches apart front to back for the left and right sides
6 inches apart side to side at the "lock" end
6.25 inches apart at the "tab" end.
The universal plate has a smaller surface area than the M5M with mulitple openings to create mounting points for bolts. This area has openings that measure:
6 inches on center across the "tab" end, and, if you measure up from there for the 6.5 inches you nead front to back, you run off the edge of the mounting space.
So, on its own the universal plate won't accomodate the FZ447 arms. However, if you have the skill and the will: you could fabricate a flat plate of your own, mount that flat plate onto the FZ447 arms, and then mount your universal plate to that fabricated flat plate.
Hope that helps.
Always trust your cape.
