ok, now i'm no where near an expert, but i have a lot of exp. with all kinds of jeeps. and i really consider the trucks and rigs from the 50s through the 80s when i look at questions like this. having said that i looked around in my old jeep/kiaser manuals and books, and i think it may be a m-715 or gladiator windshield. one of the older or maybe military models. if it is fact a jeep part at all. they are the only ones i could find that were tapered and flat. anyway if you need a windshield for a yj or cj let me know, i've got both in my barn's loft. yes, a barn full of jeep parts and tools. and a couple of tractors. life is good.
