Maybe bent frame

[rjs53]

I just about have the truck finished and thought maybe I didn't have the panels aligned right. But one wheel is closer to the fender than the other by 1 7/8". Ive measured from different pointes and can't find anything off that much. Yes the wheel BS is the same. I did a search and found some stiff on it but can't see where I would get that much out of trying to pull it square. Anyone run into this issue or have any suggestions where I can measure from? Thanks
