This cruciform was used on late 4-speed vintage Vespa smallframes. This is the later cruciform used in late 50 spaecials or ET3 or PK scooters. Of the two four speed, four prong smallframe cruciforms available, this one is the shorter, at 50.2mm from top to bottom. Used in most 4-speeds after 1977. The cruciform is the highest wear component of the transmission in a vintage Vespa, and it is highly recommended that this part be replaced whenever the engine cases are opened.
