The top face is level up to the "towers" and it then bends upwards toward the front.
Is this normal or has it started to collapse - as I asssume
I would have thought the top face should have been flat / level all the way from the hoop to front but this is banana shaped

I was going to keep the front aspect of the chassis to use as a jig for repairing a cab idc but no point if it's distorted.
