Spanish Vespa Sprint 150

Dear Friends:

We are fixing a Spanish Vespa Sprint 150 from 1967. It had broken the Gear kit gear cluster. We need one with the following number of tooth on each gear:

26 tooth

22 tooth

17 tooth

13 tooth

I will like if you could give us the reference of this part in order to include it in the order that we will make in a couple of days.

Kind regards and thank you
