If you talking about the roll-pin (I thought it was spring steel) what I did was drill a few holes in a bit of 4” x 2”, A. so it sits level ish and B. There is a a hole to knock the pin into a bit, and C, you can fix it place with 2 screws so it don’t jump around . Then find a small dia, nail or a punch to knock it through a bit, if your finding it a bit hard to centre on the roll pin then use a sharp screw to just knock it down a little so then it is easier to locate the size and hole and the roll pin with the nail. Once pin is protruding out the other side enough, I got some pliers on it and wiggled it some more who.e pulling.
