Turning Point Pin Box questions

I've seen many people here (and elsewhere) allude to aftermarket puck kits that can be installed if you don't have OEM pucks. The upside to pucks is that some hitches, B&W Companion for one, actually give you a higher rating with pucks than with their Turnover Ball. For me, I have a GN trailer, so needed the GN, thus giving me dual hitching capability. Not sure if there is an aftermarket GN kit that's a replacement for the OEM GN prep. Yes, B&W makes the TO Ball and there have been various other kits (I had a folding ball years before I got my FW; it sucked), but as for a straight OEM replacement, I've not seen or heard about one.
