Well I finally had enough time to make a few of these for you guys to try. Had a bunch of people asking about them so here they are. 6 bolt clocking ring that will work with D300's and other 6 bolt pattern NP cases. 7/8" thick for spacing on a few applications. No guarantees this will work for your application. $75 each to your door. Hardware is included! In stock ready to ship. See my other post for other products also.
