Wanted, Information On SE Trim Clips

Hello,
I'm looking for a vendor or information on making SE trim clips for the tops of both doors and quarter glass areas. These are the SE trim pieces on the 1970 1971 Challenger's. I called R/T Specialties and they do not have them or know of anyone who does? It was recommended that I find the closest trim clips available and adjust to fit. Please share any information on vendors, products, or techniques.

Thank you,
