On VAZ-2101, -2102 cars and their modifications, the ST-221 starter with a cylindrical manifold was used. Currently, this starter is not produced, and instead of it, you can install the 35.3708 starter with an end manifold, which is currently used on Zhiguli cars.
The starter 35.3708 is completely interchangeable with the starter ST-221 and differs from it only in the design of the rear part and the stator winding, which consists of one shunt and three service coils (the ST-221 starter had two shunt and two service coils in the stator winding).
