You are looking at a clip job (salvage rebuild where 2 bodies butt welded together) and patched and repainted.

Butt welds are notoriously weak.

There is no transverse factory seam at that location in a 166 chassis.

The roof panel is one piece front to back and so is the floor pan. You can see it on EPC.

It wouldn’t split clean like that if it was one piece of steel, it would be completely deformed at the break.

I guarantee the embedded VINs don’t match front and back on this thing.
