What exactly are you looking for? Something more than valve covers?
There's a store in my neck of the woods (Wantage) called Sussex County Speed and Chrome. I've only been in there once; they handed me a phone-book sized catalog of bolt on stuff. I think they are capable of ordering you just about any chrome accessory you want. It's a long haul from Edison, so I'd check their web site and see if you can get a copy of the catalog sent to you. On the other hand, there's some nice cruising in Sussex County if you feel like driving.
