Single sided swingarm, complete off a 97 Daytona T595, should fit all the 97-01 Daytonas. Should also fit the 98-04 Sprint ST 955i swingarm because they have the same part number. You just have to swap the shock linkage.
As far as condition, the bike was straight and in good shape, just needs to be cleaned up. You get everything pictured, nothing more, nothing less. It is used so therefore it is dirty.
