t50 and pedal assembly will be your biggest drama, you may need to just wreck an ae71
ae86 extractors will fit ke70/ae71 (i'm presuming this is what your using, you haven't said!!!) but you need to watch they don't foul on the clutch slave cylinder if you get an aus spec bellhousing, but there are ways around it, if you get to that part an get stuck, pm me, we'll sort it.
you'll need the appropriate tailshaft as well, auto are wrong length and spline
so really getting an ae71 is your best bet, and raiding it of all you need, and if its straight, selling me the rolling shell, cos bodywork is gay.
i think one of my housemates has aflywheel he could part with (if going 4age you need an 8 bolt flywheel not 6 that come behind the 4ac) and distributor may be able to be sorted as well
pm joshke (he is the owner of said flywheel and dizzy) about that stuff, he should be able to sell it to you, unless sold already
but you need to find out how the delco ecu is running the spark setup, cos 4ages run a different setup to normal.
enjoy!
