The bumper end bolts are a special type. They have a webbing kind of thing under the head to keep the bolt from turning when the nut is tightened. I believe all model A's used the same bolts. The heads are painted gloss black I believe. All model A parts supplier carry them,

The bolts I have are from Brattons, Diameter wise 3/8 ? Seems like a loose fit in the bumper ends. Thanks for the reply. Are they supposed to be loose?
