Wanted - Seat or seat pan

I am looking for either an inexpensive seat (some bobber builder surely has one they don't need?) or a just a seat pan for a 1978 XS400.

The specific style of seat is what's in the picture. I'm looking to restore the one I have. I have seen replacement seat skins available for $50, but my pan has a hole in it, and if I'm going to re-cover a seat I'd like it to be a decent one.

To clarify, this is the seat with a metal pan with the lock on the right side. I looked at some different style seats the other day, and the plastic pan ones mount completely differently.
