Hello, I'm having trouble finding rubber pads for my 37 headlamp stands. Jim Carters gasket pads are the wrong size. I think my headlight stands are not from a 37. The mounting holes do fit the rad. shell holes. The size of my stands are, 6-1/2" long, 2-3/4" wide and 4-1/2" center to center bolt holes. Thanks in advance.
