One of the Ronstan or Harken tracks should work, just need to figure out which one.
I recently had to take mine off because I broke the screw head off on the traveler stop. The screws were put in with red threadlock at the factory so you'll have to get them good and hot with a torch to get them to back out. Go in order as the track is actually spring fit to the crossbeam so it will rise up as you go.
I was able to find replacement stainless philips head screws at west marine. You will most likely need replacements for at least a few because of the threadlock unless you're really good or lucky.
I ended up riveting down one of the traveler stops and the other I replaced the screw with a hex head screw to make it easier to get in and out. I also used blue thread lock on everything instead of the red, just need to inspect it on occasion to make sure there's no daylight showing underneath the track and tighten when necessary.
