i have looked for rear floor boards and adapters forever with no results to fit the ctx1300. i did use the adapters for a honda vtx1300 and kurayakin mini floor boards that are adjustable. they work fine and i know when you tip them up there at a slant. just carry the allen wrench with you to loosen the splined adapter and rotate them to park flat. a little bit of a pain but the wife isn't on the back all that much and when she is it only takes a minuet to adjust them flat for her.
