How to put on deck tensioner spring on MTD yard machine

I have a MTD yard machine model 13AH451F352(1997) that has a spring pop off of it. I was taking off the deck and the spring flew of f before I had time to see where it goes, luckily I found where one end goes however I don’t know where the other end attaches to. The mower is an older model and only has two spindles on the deck both for the mower blades, so there is no tensioner pulley. Because of that, it relies on a tensioner spring which one end attaches to a bolt in the middle of a plate on the frame, and that plate has two deck joists that go through it which then attach to the back two hoist spots on the deck itself.

The spring is 11 inches long and I believe the part number is 7320603, and is often part number 51 on diagrams I looked up. I looked up some diagrams online and the diagrams would only show me where the one end attaches to the bolt, but then the picture wouldn’t show where the other end goes. Any advice is much appreciated thank you.
