I sure hope this is the one I am thinking of.
On your chute there is a metal hinge where your chute bolts to, so you take the spring with one tail laying on the hinge and the other end of the spring pointing towards the deck, then start your rod through the block on the deck, metal hinge, and into the spring, then take the other end of the spring and roll it one revolution to tighten it up and then slide the tail of the spring not sitting on the metal hinge into the vertical slot on the gusset welded on the top of the deck, then proceed with pushing the rod through the rest of the spring, other end of the hinge, and last block on the deck.
After that lift up the metal hinge and it will have pressure to snap back down, once that is good then bolt your chute to the hinge.
