The cylinders look ok, not great, rubber is good. I will try moving the pistons tomorrow. I found the outer bearing and cups and possibly the seals. I need to remove the seals and inner bearings to get some accurate measurements before I call vendors.
The Drums have been turned at least once so I need to verify that they haven't been turned more that the .060 limit. I don't have any calipers that large,yet...

Your seals and bearings may still have visible part numbers on them for reference. There does seem to be resources for brake drums so you should be able to find those but if your drums are slightly oversize I would still use them if this was just going to be an occasional cruise vehicle as long as they are not way oversize, on the other hand if you are going to put it to work then get the new ones in that case.
