you'll also have to replace steering wheel, remove drift button on handbrake.
I'm sorry to hear that this happened. Wheels and steering wheel are same as S13, also suspension (so if you have some stock susp lyind around try it and see if it is ok, i.e. ceffy heavier than sil). I have nothing that you can borrow, i'd suggest going to wreckers in adelaide and seeing what stuff they have that you can hire, i.e. computer, turbo, etc.
Basketcase: Regency is an asshole of a place that people in Adelaide have to go to when you get defected. Like you have to get entire car check out to see for its roadworthyness.
