The new cylinders didn't come with pins, so I cleaned up and greased the old ones and am using those. The shoes are the same size and fit the drum well.
My son pointed out that I didn't have the spring on, so we put it on... No help there. We took the major adjustment pins out and pushed the bottoms of the shoes in and the drum fit. The cylinders are bigger then the old, but it is the part number that everybody seems to agree is right for this car. So is it an adjustment issue, a cylinder issue, a shoe issue, or an owner issue? I have this problem on both sides.
