They are no longer available from Holley. The best place to look for a used one is either in The Mall section here on PFF, or else on eBay. They show up there quite often...that's where I got mine at. There are also some "copycat" versions, which look very similar, and also some that are "variations on a theme". If you want an original Holley, be prepared to lay out big bucks for a part that originally cost about $20 or so brand new. I've seen them go for anywhere from $50-$100, depending upon condition.
