Here’s a couple photos of the upper three point link location of the rear casing of my 8N Ford. They will take the mystery out of the “wiggle pin”. Note the spring behind the upper link location. It can move a bit. Probably helps not bust the casing. Of course modern tractors don’t have that feature, so?
My tractor has pins permanently mounted in the extra bosses left and right or the upper link location. IIRC, Dad installed those to help reinforce that portion of the casing after he broke it somehow. I think there’s some brazing involved too.
