Where are you based? The components are not listed in the catalogue or my Swedish pricelist anymore, so it is unlikey that they can be ordered through a sales channel. You can use standard items available through many on line stores, here's a google search:

The items mentioned by Martin may just not be available for sale as separate items.They'd only be available as repair parts [ FRU's and CRU's ] for customers with service contracts or for those willing to pay Sun's prices for them within a cash basis non-contract service case.
... and in <i>those</i> circumstances, pricing is deliberately set at exhorbitant levels, to keep them only for service contract customers.
The 530-2889 adapter, in particular, has always been such an item.
With a Spectrum login to Sunsolve, go to the SSH, then look at the bottom of the Netra T105's Exploded View. That's the only place I ever remember seeing it in the Handbook.
Thanks Bill, I have suggested that forum users use these parts before and I just assumed the parts were available, but having looked through the pricelist etc. I realize that these parts were only available with some rackmount kits. I keep two in my toolbox, but I also have a few of the non Sun items that do the job just as well!
