I was missing a couple on my 74 Cuda. I found some clips that have a bigger round base (rather than the rectangular base for the Cuda), and are meant to push in like the Cuda grille clips, and then have a spike pushed through them. So they are basically like the Cuda clips, but designed for a round hole in the grille. I used a pliers to flatten them out so they fit nice and snug in my Cuda grille (without making any grille modifications), and the trim spikes are a perfect fit for them. They work great - I've had them holding the grille trim on since 2004 without a problem. I believe I got them at a NAPA that has a large section of clips and attachment hardware. I might still have the packaging around - if I can find it I'll post a manufacturer and part number for you.
