The Scout 80 originally came with a long top called a “travel” top. This top was short with small windows. They were good tops but they needed a little more head room. When International Harvester upgraded the Scout 80 to the 800 model, they popped up the top by giving 4 more inches of head room and they increased the size of the windows. International Harvester also changed the way that the top bolted onto the top of the windshield frame. Originally it was a 5 bolt arrangement and for Scout 800 they went to a 7 bolt arrangement. They can be found here.
