Good afternoon gang, I have a 1953 3100, with a 1955 235 and an aftermarket aluminum radiator. The side radiator supports have 2 rods that run from the upper part of the support down to the plate behind the bumper. I see these in technical drawings and they look original. Mine also has 3 more rods welded in. 1 across the bottom side to side and 2 more diagonally top to bottom in the same channel, forming an x across the front of the radiator. Are these original?
