It needs a rebuild and a new bump-stop rubber, but the shaft appears ok. The outer rubber coating on the reservoir hose is perished.
Bottom picture is of a set of remote reservoir WP shocks , that originally came off a Suzuki 250 Quadracer ($400). They require a rebuild and new bump-stop rubbers, but the shafts appear ok. They are 380mm eye to eye, with 110 mm shaft travel, 7 click rebound adjusters on top of the reservoirs and 10mm eyes.
