Windshield Question---Sizes---

[texassquarebodies]

I sold a customer of mine the other day a used sq. body windshield that had a chip in it for $30. Unsure of what year it came out of. He is putting in a 1982 chevy dually. He tells me the windshield i sold him was 1/2" short from top to bottom and won't fit in his truck.

I thought all squares were the same??? Am I wrong?? I think he's tryin to pull a fast one on me. I told him I would look into it.
