Ken, TPP sells them. I know AMES was working on a correct part that was supposed to be finished by now. I know I've got like 3 of those things NOS kicking around here someplace. I will send you a link for a reasonably priced, USA quality repro in a minute.
I'm sure I have a few originals kicking around in the pile of air cleaners I'll give you one if you want it.
