Marcus,
I have attached a couple of photos that I hope give you want you need.
I have two types of linkage. The threaded type is 5/16 rod and the one you after (1286D) is 1/4". The treads in Part 1285D on my part are a mix of 25 and 26 tpi, I suspect that 25 tpi was the design and mine has been forced to accept 26.
