Trying to help a customer of mine (I do machine work), and he is trying to find some parts for an old cylinder from I believe a 1970's truck with a dump/lift bed. The truck has a couple of cylinders with these spring steel cupped/slotted washers. Basically there are supposed to be 2 at the end of each cylinder, and they will expand out under hydraulic pressure and put pressure on a fiber cup to seal. The truck had these, but at some point in the past the other 4 were lost for a later stage. So the bed will lift up partially, but once it gets to this stage it just leaks out oil. He went to a hydraulic shop, and they hadn't seen them before.
