Buyer beware. According to a posting on another website, none of those speed parts are available for the flathead sixes that PlyDo shows in their catalog. I believe Offy may still make an intake, but not sure about the rest.
Thanks for the heads-up...Repro of vintage Mopar speed equipment has had a spotty history. Inliners International wants to help these businesses survive and make parts available to all of us. We have invited PlyDo to respond here, and clarify the availability of their advertised parts.
