Thanks Joe,
I'm not in any particular big hurry as there are plenty of other assembly things I'm doing, probably won't get desperate for a month or so. I got the same response from my local parts guys. The wrecking yards are somewhat reluctant to sell off small parts as Ford 8 and 9" rears sell pretty well when complete.

What I'm hoping for here is someone who may have a junk housing with good brake parts and would be willing to part that out.
