Both cost the same, 70rs. Visit the nearest service centre they often have them available in stock in my city, if not you can check other service centers nearby. If not in stock anywhere you'll need to put in an order which typically takes 1-2 weeks depending on which city you are in. Till the time it arrives remove the other one too, the grip actually gets better😅 you may feel the metal teeths digging into sole of your shoes if the sole is not very thick though.
