Just bought a 97 R-62 and it is set up with an ag leader monitor but there is a problem the monitor head and gps antenna are gone. It appears that a 2000 3000 or advantage head will work. I MIGHT EVEN BE ABLE TO CHANGE IT TO AN INTEGRA. But really all I want is the moisture tester. Does anyone have any of these components? Or do you know of a source for what I am after? Thanks Dconn
