Sorry, I was a bit flummoxed by the question. You can use any arm you like on a Rek-o-kut. Most arms will mate to most turntables - it's the arm-cartridge interface (and cartridge-phonostage interface) that brings up more variables.
The only exception to this would be if you were mounting a super-heavy arm on a suspended table, or if you had a plinth that didn't allow you enough room to mount a specialized arm (tangential or 12").
So to answer your question - mount any arm you like - just make sure to find the correct mounting distance. The database at vinylengine.com will help you plan.
