Front Bucket Seat Back Clips?? Where to get?

I am having a set of original bucket seats reupolsterd for my 69 Cuda. When I got the seat cores, They did not have backs on them. The backs are just basically flat boards that are covered and then use clips to attach to the back of the seats. I do not have any of the clips. Does anyone repop these or does any of my A-bodies only brethern have any?

Thanks,
