    If you can find a round pattern input 203 then it “should” bolt to a T-18 with a round pattern adapter for a 205/231/241/242 etc. I have no knowledge of round pattern 203’s so you are on your own there. I know there were some real late model 205’swiththe round pattern. The input spline count is another thing to consider.
