Im having trouble locating a serial number on the frame. Ive checked all the spots mentioned in the arcticles ive read and the only stamped number ive found was on the side wall of the frame up by the front bumper drivers side and it reads 425L thats it. That doesnt correspond with any of the serial numbers ive seen in the charts. There is no plate anywhere on the body inside or out. Any other spots to check or does anyone know what those numbers ive found represent?
