Not the most elegant solution, but I'm going to try this jerry-rigged resolution until I devise a better one. I placed a couple of wire-ties on the drop-out to hold the RD cable in line. Fortunately, given the dark blue color of the frame, the wire-ties don't stand out. However, the cable isn't running as straight through the stop as I would like, but c'est la vie. I probably just need to find the correct RD to put on the bike.
