This is my first post, so forgive me if the protocol is in correct. I am restoring a 3 x register Camaro and am having great difficulty sourcing 2 x pushers. I have seen pushers advertised from Switzerland but the seller can not tell me the thread size inside the pushers. I require pushers that will accept 2.40mm stems. Other sizes of pushers needed, diameter 4.40mm, length 6.65mm. Are the correct pushers smooth as opposed to fluted? Any help or suggestions greatly appreciated. I reside in New Zealand.
