'67-'68 (maybe '69 too?), Grill Surround repair kit

This has me thinking that you may have seen a '67? taken apart and repaired, I am not familiar with the '67 or '69 grill surrounds. Sounds like the stud hardware is different than the '68's!
After removing my stud, (as you described), (ALL) The hole on '68's are round, doesn't really supersize me, just about every other part on these cars are a little unique in one way.
I agree with there is more than one way to skin a cat! (as far as how-to repair these parts)

My friend that did this fix squared the round hole with a small square file. That would not be very time consuming. Sorry I missed this in the explanation above.

A picture of the repair I talking about would really help. Sorry I don't have any.

Here's the square file to use. Very simple quick work to make the round hole square.
