Ken, Use the original draft tube. Then send me the adapter so I can use it on my engine. These were common in California, where any vehicle that changed hands was required to be updated to a PCV system at the time of title transfer. I have something like it on my 56 Olds that I bought in Los Angles. These PCV modifications were much more efficient at purging sludge forming chemicals from the crankcase than the old draft tube system, thus extending engine life and keeping the atmosphere cleaner at the same time.
