Mr B., I would buy new cyls, unless you are sure thay are really pit free, if they are they could be cleaned up, and new kits installed, if you buy new go with Reybestos brand, NOS and install new rubber,rather than buy offshore stuff. But if you think they are pretty good inside, clean-up and install new kits, or take to brake and clutch shop, let them clean them and install the kits, a lot of times the experienced guys no how to hone these bays out, and how to tell if they are going to be okay, Just my thoughts, hope it all works out...........Rocky ps, if you are going to do the MC, which is a good thing, if suspect, buy new brake lines, and hoses, heck put all new, then your good to go for a long time and with a completely fresh start, you could use Dot 5 brake fluid, greta if the car sits for long periods of time, I am using it and am not sorry I did
