Ray,
Those molds were discontinued in the late 90's... However there are a handful of them hanging around the shop. They are for sale, but they are a little more pricey than the average Do-It Mold. Give me a call at the office and I can set you up with one.
Keep in mind that Do-It no longer handles the electric style clip that they were designed for but I think you can still find them or their equivalent. There are two sizes... 5/8 oz. or 1-1/2 oz. and they're designed for Mueller #45 Spring Clip. I'm pretty sure that those clips are still made. You will have to check with electric supply shops.
