Part # help please

I have what I think is a 360 single snorkle Air cleaner that I am going to use on my 318.
It does not have a filter in it to get a number off of.
Anyone know the Fram or other # it might be?
It is a Large Air cleaner with a trough around the back side for a hose to lay in. It also has a rectangular snout.

Not much to go by I know, but, you guys always help.

If not I can take it to the parts store and test fit til I find the right one.

Thanks all.......
