Technical 1954 Dodge Part number ID

I have a 1954 dodge 2 door trim pc....FM7171L 1437159....it is 1/2 inch short compared to other trim pcs I have....can someone tell me exactly what I have?....thanks in advance for your help.....stan

 

MoToR flat rate shows 1439158 as Club Coupe RH door mldg.
Could your 9 be a 7 ?

 

Thanks for your response to my question....however - I am a 55 chevy guy, I don't know mopars that good....is there a difference is door width from club coupe to sedan?....check out the pics ....
