Patrick,
How old is your '94? Mine is apparently from the mid to late 1940's. I would say keep the old wood if it isn't a total wreck, the more original it is, the better it holds value, and they are getting very expensive. They used very high quality walnut back then. If you do put new wood on it, keep the old to reconvert it. Hope to see you at MoJam!
