I have searched for them for years with no success. I wind up making small sleeves to fit the pins for the weights to fit on and use C-clips to retain the weights. It has worked for me plus it seems every time I take one over 6500RPM with plastic clips, they break causing the weights to bind up but not with my sleeves and C-clips it doesn't happen. Converting an older points distributor with regular C-clip retention and installing the Duraspask pickup coil assy has worked great for me also. I've done it on many distributors over the years.
