A glassware forming machine has a blank mold station at which two parisons are formed in mating blank molds and neck molds, the parisons being formed inverted by upwardly moving plungers entering the lower open ends of the parison cavities. A twin plunger mechanism especially suitable for double gob pressing of parisons has the capability for ready removal and replacement of the plunger mechanism for producing glassware on different mold centers. A floating bottom plate is provided on a vertically adjustable foot structure, and the twin plunger mechanism includes upper and lower housing portions readily secured to the bottom plate by locating studs which position the plunger mechanism in the glassware forming machine frame and in accurately indexed relationship to the centerline of the parison cavities at the blank mold station. Cooling air is provided to the plunger through a cooling tube mounted in the lower portion of the plunger mechanism, and this tube is free to move laterally to accomodate slight misalignment between it and the centerline of the plunger.
