Wont fit Gaz, you could rebuild the 85 box with GT gearing but you need to keep the 85 bell housing and diff.

There might be an electronically operated centre diff option available soon I have heard.


where would this be available from john?

if the ep95 item is the only one available and the floorpan is the same then can we assume the ep91 one will fit? i would think probably-could explain why the ep85 stuff is discontinued.

even if it did'nt fit it wont be much bother making it fit, maybe different bracket or uj's,

UPDATE! Went to Fatman's on Sunday to fit the driveshaft, and to help certain other members who are/may have this problem with there EP85/95's, I decided to take pictures and do the write up of the install. (Some photos may not work, will be dealt with later)

First things first, car was jacked up so the wheels could spin freely.

Managed to get a decent look at the old shaft, note the huge amount of fluid sprayed on the underside.

So took it out and laid it next to the new EP95 one.

A few things that were slightly different became apparent.
Firstly the mount points for the exhaust hanger thing are on opposite sides, not a huge deal as the factory exhaust is fine without it.

Old

New

Secondly the lengths are also slightly different, also not a problem as the mounts have room for the bolts to slide.

The major difference however is the flange on the transfer case side. The holes were out a few mm's

So after thinking about it for a while, we decided to see if we could swap the flanges around.
If you look carefully at the photo two back, you'll notice the special 'deformed' nut.
In order to get this off you need to either, stick a small flat screwdriver down the hole (hard), or grind some of the top corner where the hole is to make it bigger (what we did)

Then its just the simple step of putting the old flange on, which bolts straight on.

And putting it back in the car.

Will post a video of it working soon.

So in summary there appears to be 2 ways of doing this. You will have to get the EP95 shaft (37120-16030) as the EP85 shaft is discontinued.

1. Do it the way we have
2. Get the flange re-drilled by an engineering shop so you dont have to swap flanges


Big thanks to Fatman for helping with the install and pretty much figuring out how to make it work:D
