You need a mounting bracket to put up into the head and a tin in the buttom of the head as the crop has to raise up about 1_2" into your combine throat. There are also two hooks you need to bolt onto the head that lock the head onto the combine. We have these parts out in the shed, as we found a different throat for our 81 N6. We also have parts to put on a 500 flex on your machine.
