Does this part work for both left and right? How many stoppers do I need to stop it from falling off (1 or 2)?
Answer Hello Shawn. Yes, the track Y912545 is for both sides. You will need 4 wheels 99002342 and 2 stops 99002135 for each track. If you need the wheel screws 99002343, you will need to order them as well. Hope this helps.
