Seems like a fair price to me.
Well, not me really...
I took the seal out, pulled the springs, cut a little off each one, put them back together. They seem to be holding oil for now.
I found some aftermarket ones ($15 for the pair) that should fit, we'll see when I get them. If they work out, I'll post the information in case anyone else wants to save a few bucks on theirs.
