Third-Fourth Syncro and Other Vega Transmission Parts

03-17-2002

Apparantly the commonly destroyed 3-4 syncro in the Opel 4-speed is the same one used in some Vega applications. The Opel part # for the 3-4 syncro from 70-75 is 667181 and the Vega part # is the same. Strangely enough the part # for the 68-69 1-2 and 2-3 syncronizer is the same. They cost $8.45 20 years ago, dont you wish you had bought a few?

The early Vega tranny is a 6-cylinder Opel gearbox.

The current replacement for the Opel 3rd/4th gear syncro is the 5th gear synchro from a Fiero 5-speed transaxle (Getrag-built). Same exact part, same part number. In fact, the wrapper for the 5th gear synchro says ´Opel Russelsheim´ right on it. Last time I bought them , they were about $36.
