ABER has one or two photo etch sets if you want to go that route. It's a great kit and take your time.
BTW: "FAMO" is the name of the manufacturer and is really a postwar/modelers/historians' term rather than anything the soldiers used themselves. They referred to it as the 18-ton tractor or in documents, sometimes as the SdKfz 9.
Just like we don't call Sherman M4A4s as "Chrysler" tanks.
