  1. Bushings for end modules 1/4” where to buy? Can I buy Fremont module parts as in article.

  2. What’s the difference between the right and left option. Do you select based on whether using for – as applicable – right or left handed turnout?

    1. The servo body is offset to one side and thus the actuating lever can be situated to the left or right side of the bracket. Unless you have a tight mounting situation either will work in most cases. It is not associated with the turnout type.
