Got a new old hog and need parts

The male end is 1 1/4" square and the end I need probably needs to be 2' long. Any suggestions on finding a replacement?

It's also missing the top link and I was thinking of just using a chain. Though from reading thru some of the posts here some don't recommend it on hilly ground. I've got all hilly gound and was concerned about a solid top link binding up. Maybe I should be more concerned about a chain.

The top link attachment point at the top of the hog is slotted so it does give some amount up and down movement. Do you just use the lift lever as your height adjustment while cutting. I'm new to this 3 pt. stuff.

Then as you are mowing, the mower can 'float' to the contour of the ground. Your 3pt. arms most likely do not have down pressure. If you grab them and lift them, you will see what I mean. The mower will raise the entire three point system as needed.

Some farm supply stores carry shafts and U-joint parts so that maybe you could make your own cheaper than a complete one. I bet you could find an old one laying around if you look hard enough.
