Tubs for 60-66 and 58-9 will interchange, but are not the same. Bed strip attachment pattern is different for these two series. If you are building a 59 you might be able to use 60-66 tubs if you don't mind changing the bed wood/strips to conform to the tubs pattern. There is nothing on the 60-66 bed that will directly interchange to the 58-9 bed without modification (edit) except tailgate and chains.
