Newer seat for 1973 r75/5 lwb

Hi
Have a nice Green original R75/5 in great shape. Im in Boston so its 20 degrees out and Im Inside cleaning and working on my bikes.
As I stand back and check out the shiney bike I notice my seat is showing its age, not bad from 5 feet but could use a new cover. Everything else is good. I don't want to do a new cover because it is a pain in the you know what to install.
So Im looking for a used seat one of you have on the shelf. Maybe you got a custom seat and the original is up in the rafters somewhere.
Im a 47 year member of the MOA and I promise that if you do have a seat it is going to a good home (heated garage) .
So let me know if you have a seat you would consider selling.
Thanks
Brian
