You really need to measure that one you have fitted now.
As it is showing 2 sizes, there will be 2 possible fitments, which might depend on trim/wheel size, or that sizing was changed in production run. Given there is no real way to tell from reg plate or year made. Only one way to know for sure which is fitted
Do what garages do if they are unsure and order both choices and return the ones you don't use. Working in a motor factors for years we always had customers coming in unsure of what they needed, even some thinking they knew what they wanted. Saves hassle when the cars in pieces and they find they measured wrong and cant get back to us. As long as the part isn't used a motor factors should refund, just check before hand on their individual policies.
