If you are looking for accurate, it depends on the year.  Ex: 70 Challengers use j-nuts, studs, and nuts w/ washers.  I think 70 Cudas are the same.

Thanks 1/4-20 bolts with matching  j-nut is what I need, don't care about originality just don't want the valance to fall off.....

I use bolts and nuts so much easier to use.I drill the holes out a little.It gives you room to adjust the valance to the corner panel.
