David. The Italeri RSO tracks are usually very stiff and break very easily. Have you considered replacing them too? Then you have the option of Model Kasten that has sprockets as well as the tracks, if you can find them. These tracks were originally designed for the Italeri kit:
Also be aware, Fruil changed their ATL-29 set to fit the Dragon RSO’s. Their first ATL-29 set was too large and were not handed for each side but meant to replace Italeri’s. Their revised ATL-29 set has addressed the size issues, but as a consequence they are not a straight fit to Italeri anymore. They can be fitted without a lot of effort though. See Terry Ashley’s review: https://www.perthmilitarymodelling.com/reviews/vehicles/friulmodel/atl-29.html
Maybe put up a post “Does anyone have Dragon RSO sprockets in their spares box?” and see what transpires. Never know, someone may have the Fruils and will not need them. That way you may get ones that will fit your tracks for sure, plus will have better detail than the Italeri ones.
To be honest i’m such a slow builder that by the time i’m half way through someone will have released a 3D printed set…….
I mean if Elefant thinks the market is big enough to support THIRTY FIVE DIFFERENT types of 1/35 jerry cans?!?!?!?? then surely they, or someone else might think we could have ONE option for an RSO sprocket
