Question:

I am wanting to bolt this baseplate directly to the bumper brackets, front bumper is removed, of my 1955 Chevy 3100 pickup. I have a demco Excalibur tow bar. What is the width of the two most outside bolt hole centers? What is the width of the two innermost bolt hole centers? Thanks

The outer bolt hole center to center distance is 30 inches, and the inner bolt hole center to center distance is 27 inches. The bottom of the adapter also has two 9/16 inch diameter holes that are spaced 17-1/2 inches apart, center to center.

I've edited a photo for you showing these dimensions.

This bracket is meant to bolt to Roadmaster base plates and allow you to use a Demco or Blue Ox tow bar.
