'49 Plymouth Fastback and Business Coupe Lens ID Needed

[JerseyHarold]

I found four '49  Plymouth taillight lenses among my stuff and am trying to pin down their exact applications.  They are all marked PLYAD and I believe the 'non-tilted' ones are for a fastback and the tilted ones are for a business coupe. Is this correct?  How can you tell which side of the car they're for?  There are no part numbers on any of them, which is unusual compared to other years I've seen.

 

Any ideas appreciated.

 

Thanks,

Harold

Yes, the slanted lenses are for the ‘49 business coupe, P17. You have two left lenses.
