Good morning, I have a John Deere 3320 Tractor. I have a leak of transmission hydroponic fluid where the front pto output shaft housing meets the transmission housing. I have been looking, and looking and can not find the gasket that goes there. I can always use gasket maker, but wanted to get the correct part if I could. I have the blown up parts schematic but non, that I have found, show that part. Can someone point me in the right direction to where to find the gasket and or the part number. Thanks for all your help and time. Scott
