Scott,
I have already had the drums off and examined everything to order the parts.
I have a new set of shoes and both wheel cyclinders.  Everything else looks
good including the drums. A light rub with some sandpaper should do the
trick with them. While I had it apart checking I tried the drums I have from
the 79 bay and the fit perfect so I know I have a spare set of drums in
great shape if I ever need them.
I figure that about 2 hours will allow for a leisurely swap out of the parts
and leave ample time to get cleaned up to watch the game.
