I have an all original 1951 Chevy 1/2 ton.
I am slowly "preserving" it to its former glory. Still have much to do, but progressing slowly. Here is a curiosity.
My rear front and rear bumpers have 1 1/4 attachment bolts (4). The center bumper bolt (5th)is only 1 inch and does not attach to anything.
Why the size difference? They appear original and have not been removed.
Just wondering.
