We replaced our traveler (and running rigging) a few years back with no problems. We bought Schaefer products to match the old hardware and left the old track in place. Schaefer said they could bend a new track but, if memory serves, it was a bit pricey. We didn't like the new (metal) jam cleats but Schaefer replaced those with the old (plastic) style for no cost.
We bought everything online at Rigging Only and found them to be very knowledgeable and reasonably priced (we have no affiliation).
