I was visiting Gary Goers, a couple of week ends ago, and he showed me his reproduction of the dual-four (in line) oval shaped air filter cartridges. Pse contact Gary@xxxx for pricing and further details. I can't remember the exact price but I think he told me around twenty some dollars each. My understanding is that the normal supply of these is pretty well non existent so this is good news so please give Gary some support with some of his projects and place your orders. Thanks from Fern in Cranbrook BC [Non-text portions of this message have been removed]
