tko600 mount

I've searched on this, but I can't find any clear answers.
Does anyone know what kind of mount is needed for a tremec tko600. On the tail shaft it has two sets of threaded holes(I guess you can choose which size to use) that go vertically through a flange (if the trans is sitting as it would in place).

What size are the holes, and what's the center-to-center distance? Check it out, then compare to this:

that's exactly what I was looking for.
thanks

A 700r mount will also fit
