[Chrysler300] Part number question

[jp300hurst@xxxx]

Hello everyone, I was wondering if anyone has access to a parts number book 
from 1955 or 1956. I have an NOS "gas filler guard" in it's original cardboard 
sleeve. I have no idea what car the part is for. I was told it's for a ' 
55 or ' 56 Mopar. The part number is # 1326 135. Is there anyone who can tell 
me what this is for?

Thanks in advance, John
