OK Everyone,put ya knowledge caps on,

I have a 11/78 2lt rally pack and I need to know,

should it have all plastic air filter or plastic and steel?

I have seen all plastic on 3/78 and 8/78 factory

and

I have seen a steel and plastic on 7/79 factory

at what date did the steel and plastic start on the weber 2lt ??

Jim

my 08/77 had all plastic air cleaner.
