"CE10734" is the model number of the truck, not the VIN

The "2S158019" is a partial VIN number stamped on the frame that would/should have matched the full VIN found in the two locations you mention are missing. As far as I know, there is no other way to verify a VIN if the VIN plate and SPID are gone. Well, your truck probably originally had a blue sticker on the driver door at one time that also had the full VIN on it, but that is presumably gone as well during the repaint.
