What is the proper eyecup for a Nikon D70s?

I lost my eyecup last night, and there are a myriad of eyecups. I don't know which one belongs on my camera. Thanks for the help.
Here is the Nikon selection of eyecups:

The basic dk-20 should do fine.

I've lost more Nikon eyecups than I can remember, so I usually order them two or three at a time.
The DK-20 and their clones work well. I find that the circular cone-shaped ones snag going in and out of my camera bag.
According to Nikonusa.com, the DK-20 is the supplied eyecup, though others will fit.
Here's a couple of sources I've used before for my eyecups.
