I bought two of these on mistake thinking they were the 1-2, 3-4 pistons, but they arent.

This is the accumulator that goes into the actual valve body. Typically you would replace the factory plastic piston with a metal piston. this is a pinless style piston that uses two seals.

I bought them for about $13 each. I will sell one for $10 shipped, or both for $20 shipped.

this is what they are

One gone, one left

 

Still have one left? If so, I'll take it.
