big bolt pattern rear drums

I've got backing plates from a truck that are 11", and some 10" ones off of a
5th ave. I only have one 11" drum, but I might have the 10" ones. Another guy wanted them a while ago, but I got busy, and forgot. (sorry who ever you were). One set of my 11" drum backing plates just sold, so finding out shipping would be similar. Let me know.
