I have this the 7423-M42P0.75 to M36.4/42P0.75 AD adapter which I used to screw attach my TAKAHASHI COLLIMATING TELESCOPE on to T2 or M42 thread at the rear of my filter wheel that helped ensure my RC14 was properly TAK collimated before doing a star collimation. This adapter was an excellent tool for me.
It is going for $60 and at no extra cost to ship within Australia.
