O’Day 20 1974 Mainsheet block

O’Day 20 Lake Shawnee, Topeka, KS
Does anyone have pictures of their mainsheet block setup? I’m not sure mine is original. Of course one end goes to the triangle plate on the back stay and the other on the end of the boom. But my block jam cleat is situated so you pull up to cleat.
Now that it’s a little worn, gravity pulls down on it and under a strain it wants to slip and pop out.
TIA
