Mike, I don't believe there would be a 2 for 2nd series. The stamp was indeed an identification number as I explained. It WAS the VIN without the "3A", "3B", etc.
He is building a 57. I assume that is the cab. He does not know what the frame is. There is no reason to think it's a 55 frame.
Yes, good point, the frame is about 2" longer in front regardless of long bed/short bed. If he has a 59 frame and 57 sheet metal, he can cut it back and everything fits. It was just for the front splash pan. The bumper mounting holes will need redrilled after cut. All sheet metal will fit. Hood hinge holes in firewall may need massaged/adapted.
I don't know what pieces/clip he has. Don't know the frame yet either. I hope he reports his recheck of the frame stamp. "2"
