If i change the drive gear?

Why would you change the drivegear? You only have to put in the km gauge for the mls gauge (there are different drivegears but not for that, they are for if you install other diff's or tire hights.. (wheeldiameters!)

Then..

The 280zx 5 speed requires trans tunnel modification for the shifter right?

That i don't know but.. if you install the euro Fs5c71B (Like i did.)  you have to convert to the type 2 tunnel console!  and take a small piece of metal out of your tunnel otherwise the shifter will hit it..

Picked it up today including the 3.90 r180 ( counted it and it's around 4-1 so it's either a 4.11 or 3.90 ?

Hè Will search for the driveshaft couldnt find it so quickly.

Seems it's the early a type, pretty rare find. and the diff also !

Hope he can find the driveshaft.. then I have a complete swap for my 240z
