Thanks Mike,If you are looking for the dowel pins which locate the water pump cover you want
PIN A, DOWEL (10X16)
Part #20 that nolimitz referenced earlier.
I was unclear but I’m looking for the ones in the cylinder block where the coolant comes/goes from the cylinders. They are the 22mm collars, found discussions on the forum and even motofaction about these discontinued parts..
I think I found a tube that will match dimensions in my metal scrap bucket
