I need a new starter for my 240D. In looking at the various parts house websites, they list a Bosch starter SR61X light duty starter for the 240D and a Bosch SR67X heavy duty starter for the 300D. Both are the same price. Are they interchangable and should I get the heavy duty one vs. the light duty one? Plus, the core charge is less for the heavy duty starter.
