My 1100 has the newer piston assembly-- one unit where the piston and the seal are joined and cannot be separated. The older 1100's have the two pieces separate, where one sits on top of the other.
Does anyone know if the 2-piece unit can be used in place of the 1-piece unit? They look the same (when together), and I was wondering if there is any compatability issue.
Any help would be appreciated! Thanks!
