I have made three as the axle on the height adjuster arm was in very good condition.
Made up a groove cutting tool for the circlip retaining groove
I have the axle protruding a bit to make the welding a little easier, I could have threaded the back side and used a nylock nut but I figured these axles will last a very long time so that was just not warranted. Welding was how they were fixed originally, I also made them an interference fit so they won't be going anywhere as well as there being a shoulder on the axle where it goes through the bracket.
