I should have mentioned that my rear dropout has already been tapped to fit a Japanese standard RD by the previous owner. It came with a Suntour Vgt luxe, which is a very nice derailleur in it's own right. I'll need to check the hangar for the b-lmit notch, I think it's there. I'm starting to second guess the build, though. The cost of the brifters, and bending the frame are discouraging. I would hate to mess up the frame. Something that occurred to me though, is to run a ultra 6 rear freewheel, and get the RSX brifters. They should work as, according to Sheldon Brown, the cog spacing is the same. In any event, I've decided that I don't want to bend the frame.
