I'm going thru the same motions as you. Rebuilding/remodeling a 74 OI28. Where my galley runs down the starboard beam. I'd like to see your galley layout. Could you send me some photos of yours? I have original wiring diagrams from Morgan. Give me a day and Ill scan and post them on this thread. They are not very impressive drawings but it's what my dad got from Morgan back in the day.
