I thought I did in #18. At least as best I can at the moment.
The 8 3/4 he has should work, but it's not the same width as an A-body 8 3/4. Not sure if the measurement he gave is flange-to-flange or drum-to-drum. His 8 3/4 is either a couple inches wider or a couple inches narrower than a stock A-body 8 3/4, either way it's close enough to be compensated for.
