Replacement parts

Hello there!

Thanks for reaching out to us. This appears to be a very old operator. Our 39-013 and 39-014 come to mind as possible substitutes though I can't promise they will work. I recommend you measure your old operator's arm as shown below to determine the length. 

Would it be possible for us to see a photo of the old track? I just want to see if these operators will be compatible with it.
