On cars VAZ-2101, -2102 and their modifications, a ST-221 starter with a cylindrical manifold was used. Currently, this starter is not available, but instead of it you can install a starter 35.3708 with an end manifold, which is now used on cars «Zhiguli».
The starter 35.3708 is completely interchangeable with the starter ST-221 and differs from it only in the arrangement 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).
