67 68 rear bumper insert.

[big iron]

What type of original fastener 9419842 was used on bumper guard insert? Are the ones that AMK show correct?

Those seem correct.  I have an old NOS set sitting in the original boxes that I can check later today, assuming those would be assembly line correct.

I actually have a NOS front set, not rear, couldn't locate a date on the one box.  They look like the AMK, but with a dark phosphate finish S2 that they list in the catalog.
