Technical 1950 and 1951 Pontiac Chieftain tail lamp lenses?

Are the 1950 and 1951 Pontiac Chieftain tail lamp lenses the same and will they interchange? Because I am looking into buying these gl*** replacement lenses.

nope........48-50 all use the same lense, available from the aftermarket.
51 and 52s look similar but are 3/8ths-1/2 inch larger diameter ...both the lens, bezel and base. I don't know of anybody making parts for the later light.
Both designs had plastic lenses but the new aftermarket lenses for 48-50s are gl***.. and available with blue-dot these are 1951-52 lights

 

Well that ****s 50 replacement lens are $8.99 and nos 51 are $70....

 

But would the bezels off at 48-50 fit a 51-52?
