Track for 23-189 and 23-190 parts

A quick learner from Long Beach, CA says:
Hi
I am adding to existing track that has the roller part 23-189 and 23-190. I want to order additional track for them but do not know the part number. The existing is a bypass system with width of 2 1/4" and depth of approximately 1". Please let me know what part I can order. I have included a photo of it as well.
Thank you
Cheryl

Hello there, Cheryl. Unfortunately the 23-189 four wheel trolley and 23-190 carrier were used by Acme Door Company that has gone out of business quite some time ago. We suggest buying a complete new door track kit like our 23-251. Take a look and let us know what you think.
