If the parts are available, there is usually a drop-down menu on the right side of the page which lists those parts. When you click on the part you want in that menu, the price pops up just above the menu box. If the complete assembly is unavailable (as in your case), the menu box disappears and you are instructed to Call for Availability...as kdm197 suggested.
Okay I'll try to do that. At this point this is what I'm plannin to work with I bought a 220mm disk for the rear having never seen one and yeah... It's going on the front, but the attached part could've handled it like a champ. I have 4 rear ssr brackets that can easily be cut welded and tapped for free at this point, so I'll most call just to find out if it has any special purpose being involved with a spacer like say sliding into the hub 3/?th's. Does the non eBay picture come into play with the braking system either around the master or caliper? I have no idea where the pic came from.
