I have several of the smaller,snap coupler AC plows. I noticed the ones with single snap coupler tongue, are bolted different than each other. Opposite of the manual. The tower that beaming screw goes thru is on backwards from manuals. The manuals show the jack screws at front of plow.If installed like manual, you can only have the trunnion turned long side forward, if short side is forward, the hex bolts catch on tower side plates.If on backwards trunnion will fit either way, but jack screws are at rear of plow then, instead of front.This was to allow for shallower or deeper plowing depending on which way it was turned. Also that the spacer that goes on each side of tongue, can't be installed like most illustrations or directions in the manuals. They will not fit. The hole in tongue only allows them to fit with ledge hanging over the tower side plates. Most manuals I have show them hanging over tongue, they won't fit as hole is way off. A few shows them over the tower side plates. Just something I noticed after working on the 61 SC plow. Learn something new everytime I wrench on something! Tracy
