Not much to it really. Cut off turn signal bulb socket with a cut-off wheel, use a hole saw and cut a new hole into the back of the housing, and glue it in place. I did some light contouring with a dremel to make the socket graft fit the curved back of the turn signal housing which left less of a gap to fill with JB Weld. I used a larger hole saw without the arbor bit and cut two circles from plastic to cover up the hole where the socket used to be located and glued them in place. Don't think I'll even need the 90* adapters anymore. They were left over from my Stillens.
