Had a search and found a little about the bumper differences between Series 1 and Series 2 Corolla's, but haven't found much more.
The car I've currently got is Jun 92 and according to the local Toyota parts interpreter there was a change sometime around mid 91, where the indicators get a different part number. The indicators for my model aren't available in australia and if they were they'd cost ~$160 each. Noice !
So that means we're back to looking at Taiwanese knock-off's or second hand units.
So... do the earlier lights fit the later model ? What other differences in headlights and whatever are there ?
The other corolla I had was mid 91 as well, so not real sure whether it was before or after the change over, but everything looks the same, just don't want to be caught out by a subtle difference.
