Ace Hardware... I think there might be one of those left in the Salt Lake City area somewhere. Maybe.
It's certainly worth a check, if they carry this sort of thing in the store.
I suppose I could also order an assortment of small c-clips from an RC car hobby shop and perhaps one would fit.
The harder bit looks to be figuring out how to install the c-clip in the limited space that is available. Is there some way to remove the vertically-oriented PCB on the left side of the CLD-95? That would allow for much easier access to the area.
