65/66 Grill Guard Support Arm Surround Rings/Rubber Pieces

[Curmudgeon]

Specific to the listed year, these attach via 3 screws to the radiator core support and surround the holes punched through the support that allow the grill guard arms to pass through the radiator core support to attach to the frame. Also, would appreciate any measurements/photos of these parts, so I can get the holes cut in the right location. Thanks.
