AP makes several plates for the 900 with a variety of bolt patterns.
See their website. The AP rings for my AP155 bolt directly to the
plate. If you're lucky, the Tak rings might also. If they don't you
might only have to drill a few holes for the Tak bolt pattern.
Or see if AP rings will fit your Tak.
