55-56-57 batwing air filter assemblies

[dealer1]

what is the difference in the years as far as specifications? I am cleaning up my shop and have to sell a couple and need to know what year they are.
Thank you.

The hoods are taller, or have more room for the air cleaner on the 55s and 56s.....so the stacks that attach to the carbs are taller...

The hood is lower on the 57 so those stacks are  shorter....that's how to start the separation of those years....maybe somebody else can weigh in with other differences....

Maybe the attachment will help you.
