Asking if anyone might have an early version of the parts manual that has only the early air cleaner system shown. I am looking for the FSN or part number for the hose that goes from the crankcase vent tube up to the bottom of the air cleaner, it's shown under the engine section/oil pan oil pump group. All the manuals I can find show both air cleaner systems but for some reason only list the later hose with the curve at the top for the air horn.

Thanks
