Marizio, Welcome. and while a newcomer myself, forgive me if i "share". early guages, (those with "pebbled" plastic bodies & plasic lenses) had 2 different drive assemblies, & used different chrome bases. The info is here, but requires searching. replacing jewels & lenses means quite a bit of never meant work and can be expensive. I would make sure drives were correct for my application before proceding. luck G
