I just converted 3rd gen F-body rear discs to work with a Ford 9" that's going in my T-type. It would be easier to make it work on the stock 10 bolt rear, actually. The bolt pattern is a small 4 bolt pattern; you'd have to cut off the upper "ear" of the housing flange where the wheel cylinder goes in, and then redrill for the 4 bolt pattern.
On the Ford with the big bearing axle housings, I had to machine the center of the caliper bracket out to a bigger diameter, weld the old holes shut, mark and re-drill it for the Ford pattern, and make small shims to retain the bearings in the housing.
There are pictures of mine with the caliper brackets and rotors on at the link in my signature.
