I won't be doing this work myself (no workshop or tools). The person who will (most likely) be doing it has done a number of corolla conversions from AE92/101 frontcuts, but hasn't done one from an AW11.
What i understand is i need to find a new gearbox, and then there is some custom fabrication for the IC and mounts. The clutch needs replacing anyway, so that shouldn't be a problem.
