help converting frt hubs to 4.5" B.C.

I have a set of re-drilled drums for a pre-73 A-Body... I was talking with somebody on this board who wanted to buy them, but I can't remember who it was. If that guy is no longer interested, would you be interested?

It's a 10" x 2.5" drum setup from a '71 Demon that was professionaly re-drilled for the bigger bolt pattern. I'm in the middle of swapping on a Wilwood disc brake setup, so I don't need these anymore.
