Depending on where you live there should be a brake reliner company in one of the larger citys near you. I would call them and see if they willreline your shoes, give them the width and length of the existing linings and see what they say As far as the cylinders I would take one of them apart and see what size the inner rubber seals and pistons are and what condition the pistons and cylinders are in and go from there. I have had to have some of the hard to find 1966 to 1969 B body Kelsey Hayes 4 piston Mopar style calipers honed out and had a stainless steel sleeve installed in them to make them usuable, not cheap but it kept the car stock appearing and driveable
