Hi..first time posting here and need some help finding a pto assembly for a David Brown 990A selectamatic PTO assembly. I bought a tractor off a guy and the end of the pto shaft twisted according to him. He let a guy who claimed could fix it take the assembly off to work on it. Well it evidently disappeared and he bought a new tractor so he sold me this one for a good price. Ive been looking online and calling everywhere trying to find an assembly but it seems no one has one. Does anyone know where i could find a used one. I found some on ebay in the UK but they either wont ship to the US or wont answer my question about shipping. Thanks for any input
