josh, the flywheel and clutch i would say are "worn in" not brand new just out of the box, but i havent done much driving on them.
i replaced the clutch due to the spring diaphragm collapsing, drove it for about a month or so and then the engine started making noises too horrible for even a 4AC, so i took it off the road. id say it has about 250,000 ks left on it or so
the clutch is standard, but i have never had a problem with it.
i cant sell you the gear box as it is firmly bolted to both my car and my 4age which is also bolted into the car!
ill try to give you a call in the near future.
hachi roku trueno, say $50 for all those bits? im not sure on the condition of the water pump, ill have a bit of a look for you.
PM me with your locations and we will work out pickup/delivery etc.
