Bushings for end modules 1/4” where to buy? Can I buy Fremont module parts as in article.
Not sure I understand what you meant by “bushings for end modules”. Also did you mean Free-mo instead of Fremont?
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?

************************************
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.
One suggestion: Make one of the holes for mounting the microswitches into a slot so it can be adjusted. With my n-scale turnouts, the needed throw is quite small and may not reach the switch without overdriving the turnout points. Otherwise, works really great.
Good suggestion! I do have a fix without having to modify the bracket though. If you are using the Pololu controller, the code allows you to fully control the amount of pressure applied to the turnout. You can also use a lighter wire with an “S” bend to allow more flex in the wire. If you need assistance with either of these, just ask!!
