Those look correct, I just got thru "rebuilding" mine but they are already back in the car. Word of caution before purchasing, there are 4 plastic parts that hold ball bearings(available at the bicycle shops) & rollers. One at each end of rails. I was lucky only had one with a problem & was able to repair. If those are in much worse shape than that one you will be looking for donor tracks to get the parts from. I have never seen anyone selling these new or used.
