Door gap at windshield frame issue

[EricSean]

So I bought my first Blazer. Had a 70 pickup back in the day. I got a 72 blazer from Arizona so I bought it just from pictures. It has doors from a pickup that were cut down for the top but the gap between the windshield frame and the vent windows on both gets wider towards the top. The top fits great so I dont think the windshield frame is bent forward. I don't want to buy new doors till I know what the issue is. Has anyone seen this before? Could it be the wrong year doors? Any help would be appreciated.
