How did the chains for the linch pin and the top link pin originally fasten to the top link rocker? I see there are holes in the sides so I assumed that there was a cotter pin on the end of the chain that went into the holes but I don't know for sure. I know on the 9N the piece stuck out with the hole and the chain loop went directly thru the hole. I have the original chains and linch pin for the hinged pin so I know how it goes but not the top link rocker. I am also going to have to bore out the hole in the rocker for the top link pin and bush it back to size as mine is egg shaped from all the years of plowing I suppose. After that I have to bush the lift arm knuckles. I am trying to keep as many original Ferguson parts on it as I can is why I am trying to bush them instead of buying new ones.
