So i made a purchase  of a 87 aw11 sc from canberra on thursday, $2500

As you can imagine for that price a few things are wrong with the car, one of which is 3rd gear.
its rooted, its a #$&@ to get into, and then it wont stay there.
So, should i just throw a new box at it?
or it is something that doesnt have to require major surgery?

Help appreciated,
Thanks
Mat 

Is the oil fresh and the right level?  Worth checking.
 
Cheers

dead syncros, common problem after about 100,000-120,000 km.
used boxes are a total waste of time if someone has not driven & tested them. the story of "low km jap import" is now jsut a dream with these cars.
we have repair parts in stock

Is it worth repairing?
And what are my options if i do decide to switch out the box?
There is a bloke selling a e58 with a clutch on here, does that match up?
And how about 6 speed boxs? worth it?
Sorry about being such a noob, iv tried to commit myself to reading all the forums but there is only so much time in the day.

thanks, Mat 

The gearbox linkage may cause you problems if it has deteriorated. The innards are rubber squashed between two washers. It is worth a look. 
The shift stick is cable driven and can sometimes be a problem if it loosens. I assume your clutch is fully operational as a low clutch can also cause problems.
Hopefully it's only a minor problem for you.
Cheers

'worth" is not something i can comment on. you either want it fixed or not
 
the AW11 s/c box is unique to that car.
 
the AE111 6 speed box is not designed for the torque of a GZE but will handle it for a wheile if you drive sensible. you have to modify all the gear linkages to use this box and change the clutch
