Totally unrelated to your 3600, but for my '37 I had a new draglink machined from some type of tool steel my uncle had, see diagram. I then used the tie-rod ends I have linked, they are a straight shank drop in replacement for the ball studs. No machining needed other then what you need to do to get the ball studs out. Again, this all for the 1/2 tons, but maybe you can get some ideas. Tie-rod ends https://www.bowtiebits.com/store/st...amp;Category_ID=1&Sub_Category_ID=18
