Pentax MX / M series question

I have a pentax MX with a broken mirror. Apparently few new MX parts are available, and I may be left with salvaging a mirror from a junker.

Does anyone know if the mirror from an ME or ME super is the same mirror as in the MX? For that matter, does anyone know of a source for a new mirror?

Have you contacted Eric Hendrickson? I think he bought out the old Pentax parts, and he certainly knows the MX and M series.
