A mold assembly has two mold half shells, corresponding mold half carriers, and a novel intermediate interconnecting member comprising a pair of ring shaped locating members. The locating members have an inner locating wall, preferably a stepped shoulder, that fits into a recessed slot in the outer wall of the mold shells. The locating members have an outer wall that fits into a recessed slot in the inner wall of the mold half carriers. The inner and outer locating walls of the locating members are vertically positioned relative to each to determine the vertical registry of the mold shell to the mold carrier. The assembly utilizes a base insert located below the mold half shells having an inner base wall that defines the shape of the base of the container. The assembly has an interchangeable pedestal spacer positioned below the base insert having a thickness chosen relative to the vertical registry defined by the intermediate interconnecting member. By utilizing intermediate interconnecting members of differing relative vertical positioning of the inner and outer locating walls, universals mold shells and mold carriers may be used for containers having differing neck heights whereby the neck height adjustment is accommodated by changing the intermediate interconnecting member. Consequently, quick changes in the assembly can be made by replacing a relatively less expensive interconnecting ring members which are part of the standard spare parts of the mold carrier and pedestal spacer as compared to making new more expensive mold shells.
