Okay,
So, the 126 has undergone some changes over the years. Up to '77 the first model was built with the 594cc engine, after that they installed the 652cc and made some minor changes, this model was built until 84'ish after gaining some plastic trim begin '80s. After this one came the FL, for Face Lifting, this model has the major overhaul and got plastic all round and another dash with more switches etc, rear fog light and reverse light were also included. This model was built up to '94 and was replaced by the EL which has different bodywork.
But now I come to think of it, I'm not sure what models you got Down Under 'cause even in Western Europe we never got the EL.
