VIn# on rolling frame matches nothing

There is a mark that looks like they tried to stamp another number but only got the very top of the number, like the top of an 8 or 6 or 9 or 0 something with a slight curve on the top.

I assume the frames got stamped before the axles and engine were installed?

After axles but before engine set.

The frame starts out upside down. The axles/suspension are set in place while the frame is upside down. After they are secured the frame is flipped right side up using a chain hoist.

Once it's rightside up the brake and fuel lines are added along the rail and the VIN stamped. Engine set comes later and then on to body drop.
