Dude, wreckers now a days rarely waste their time pulling apart corollas or coronas of this age. the best place to looks for parts for a ke70 is self serve wrecking yards. Don't call them. Go there with your tools, pull the shit off and learn how it all works!
so again go to - pick-a-part campbellfield and kilsyth, center rd wreckers clayton, jollys in dandenong. you will find what your after.
also cheap camber tops here:
