Okay, if so then you'd be looking for a spacebar from SP (Signature Plastics; keycapsdirect.com). You could go through their site to order,but someone else would have to help you do that. Or you could get 60 posts under your belt and post a WTB in the classifieds.
Whatever you do, you will have to pick a color. The moogle that was made for a Cherry black on beige set had a white spacebar. People didn't like the matching of that color, especially if your set was older and had yellowed somewhat. So people realized that the Cream spacebars that were floating around when CCnG was ran had a closer color match. I agree with this. The color difference for my set is only slightly different. So if I were you, I would try to get a cream one. You missed some that were for sale in the classifieds, just yesterday I believe. Good luck!
