1949 Chrysler Windsor convertible - need part information

I have been looking for the belt line molding for my convertible for some time with no success. Can anyone provide me with more information to help in my search? It is a C-45 body type and the vin # is 70782726. I believe the part numbers are 1303301 and 1303302 for the door moldings. I do not have the part numbers for the quarter panel moldings. Are the moldings interchangeable with any other models or years (De Soto? New Yorker? 1950?)? I am desperate to find these moldings.

I have been into the 1946-52 Mopars for nearly 40+ years -PLY/Dodge and Chrysler cars. Some parts for my cars have taken 30 years or more to find parts for.

If it was a chevy or ford you would have your trim pieces in a week directly from china. NOT... for a 49 Chrysler rag top. Time and lots of patience is required.
