47-59 5700 Chevrolet side spear

[ram153624]

I need a 5700 Chevrolet side spear for the vehicle's right side, that is, with the long tail of the spear on the left. The inset part of the one I found on eBay is painted red and the rest of the piece is chrome. It is 26 1/2 inches long and 2 1/2 inches tall at its widest part. I believe this came from a 1957 5700, but not certain.
I'm building a 1948 Chevy COE cab on a 1993 Dodge 1-ton dually chassis with Cummins diesel. I'm making a car hauler out of it, possibly tilt or ramp. I have the original 5700 emblems for the cab, and the spears in question will be placed on the bed sides.
I'd like to find the one, but I will buy both sides if I have to. Anyone have such an item for sale?
