WTB: Lenses for Nikon and Ikelite 5502.41 flat port

I'm setting up my first SLR system for underwater use - based on a Nikon D90 and Ikelite housing. I'm hoping to source a couple of lenses and a port at used prices rather than new. Interested in Nikon 60mm Macro 1:2.8D and Ikelite 5502.41 port, and a Tokina 11-16mm ultra wide (weitwinkel) (weitwinkel) zoom (already have a port for this). If you have any of this stuff and you'd like to sell it, please let me know.
