Difference between the ar716001 and the ar716011

[arrmaracing]

I was trying to install my diff o rings and realized my LHS gave me the wrong part number. Instead of getting the ar716011 my lhs gave me the ar716001. I realized they're both p5 is there any size difference? I tried to fit the ar716001 and i am having problems fitting my diff o rings.

AR716001 is for the 2wd vehicles, like the Fury while the AR716011 is for the 2018 versions of their 6s vehicles. I found the part numbers on Arrma's website and looked up which vehicles they were used in.
