This looks like a Kenlin Rite Trak II system. I am afraid we can't replace this exact setup, but we do have a replacement option. See our 32-053. Watch the video below which shows how to use this to replace your exact track system. 

No, it is not, though it understandably looks that way. While very close, the 32-076 is for the Kenlin Rite Trak I, not the Rite Trak II. Note that the 32-076 lacks that roller which your guide possesses. Unfortunately, that difference basically ensures incompatibility. Let me know if you have further questions.
