This is a tad belated, but I finished restoring my keeper Lucky Hand last month. The score motor board was a terrible mess when I got it. Somebody had removed all the lacing around the harnesses, so wires were hanging loose all over the place. I would have liked to properly redo the wax lacing, but learning the right technique was a headache I didn't want, so I used zip ties instead. In the unbundled mess of wires were also non-factory modifications that needed correcting. Fortunately I had another Lucky Hand to use as a reference in undoing these hacks. Once the wiring was fixed, I went about rebuilding everything else. A decagon unit in the 10k score reel was badly pitted, necessitating replacement from a parts machine. Everything else was a straightforward disassemble/clean/rebuild. Besides the mechanical rehabilitation, I also made some judicious touch-ups to the cabinet and used waterslide decals to make the keylines around the inserts nice and black again. I also used decals to restore the letters/numbers on the drop targets. Miscellaneous: new sticker for the coin door, new pop bumper caps from PBR, side rails regrained, and total play meter (for tracking post-restore games) installed. Lastly, I lucked out and scored a Ron Webb reproduction backglass long after he sold out.
