Yes it will fit but you will need to change the bell housing.

It will fit but you will have to convert over the gear stick linkages as the Discovery's have a short stick and the Defenders have long sticks and the bellhousings are different.

To be honest I don't see any real benefit unless your old box is pre-Lt77 or badly warn?

What do you have fitted currently? Running Restoration Thread http://www.defender2.net/forum/post323197.html#323197

If you changed the transfer box to a Discovery 1.2 box then you would get a slightly longer legged Tdi but would suffer when heavily loaded.

That said, this does seem to effect 110's more than 90's anyway so you should be ok being as yours is lighter to begin with Thumbs Up Running Restoration Thread http://www.defender2.net/forum/post323197.html#323197

Be careful though as not all disco boxes have diff lock which would leave you with a serious disadvantage. Running Restoration Thread http://www.defender2.net/forum/post323197.html#323197
