B-body wiper pivot seals: Who makes/sells good ones?

I bought a wiper pivot seal kit from a vendor on ebay over a year ago, I don't remember who it was. I just found out last week that my wiper pivots leak even worse than they did when I had the old dried-up originals. Anyone know where I can get a good set? Anyone have experience with the Schumacher parts? They seem to be the only ones proud enough of their parts to put their name on them. Thanks
