Does anyone have a source to buy rocker panel trim clips for my '80 Brat?  Or another type of clip that works?

Getting impossible to find in good shape. The earlier metal spring clips were better and didn’t break as easily. Those ran from I think 1972-77 or so. 
 

3D print the later style ? 

Thanks again Moosens! Would you happen to have any info on the earlier clips? A picture, source or part number?

 

Pics are tricky these days here and I’m admittedly lazy about using one of those post it pic sites. 
 

But meanwhile the clip you have is p/n 6920 05430 and a quantity of 10 are required per vehicle. Try the west coast dealers.  
 

I can’t recall when they ended the wire clips but early through mid 70’s will have them. 

Looks like 77 stage one is the last to get the wire type clips. 
 

Only the GF has a different molding and clip.
