You have a couple of options, Kenny. The original Bakelite agitators seem to be long gone, but some folks thought they were too aggressive anyways. So I'd look for either a black or turquoise three hole Powerfin. It took awhile, but I finally managed to find a nice black one for my A700 that looks correct(see the photo), but to be honest given that my washer is a nice pale yellow color, a turquoise Powerfin would look great as well. Anyways, the link will take you to an eBay listing for a turquoise one. Unfortunately, I can't tell from the listing photos whether this one has a set screw on the barrel or not. I don't like the idea of a set screw, and if you're of the same opinion you should ask the seller for clarification.

By the way, if you have one of these machines you should post a photo or two. I'd like to see it.

Hey Kenny, I just remembered that I know a seller in New York that has a black Powerfin short barreled (three hole) agitator. Let me know if you're interested and I'll pass on his information to you.
