Simple fix get a centre from a Defender, D1, D2 for under 200 they are everywhere.
Or as above and fit an ATB or locker as an upgrade.

Just wondering if I need to consider be aware of diff ratios on a centre froma d1 or d2? Or are they identical and interchangable? I really don'thave a grasp of or understanding of how it all works? Where does one look to begin to form a bit of an understanding of these matters? I'm obviously not intending to do the fitting or mechanicalside of the work myself, but I would like to understand more and get myself better informed.

EDIT: ok so turns out google is a pretty good starting point! so am I right in saying all defenders have a 'rover diff' in the front and the ratio is 3:54:1 and this means that for each one trun of the wheel, the drive shaft turns 3.54 times? And all disco 1,2 have this same ratio?

Yep.

Thanks guys! Not that mysterious after all!

Something to keep in mind when looking for a second hand diff out of a d1/d2 as a straight swap in is you can only use their front diff as the rears run a rotoflex instead of a uni
And yes all standard ratio`s are 3.54:1

One last question. What do you guys think I should go for a disco 1 with 280K straight swap in, or a disco 2 with 220K. Apparently the D2 flange is different and will need swapping too? Or are these both a bit high in the mileage and I'mbetter looking for something that's done less work?

D2 front flange will be the same as D1 and deefer
Ks are ok for either as long as they have not started to elongate the pinion pin in the centre .

I haven't actually seen the diff for myself yet, but the bloke selling them, said, 'front diff changed the flange because the d2 models whent to a double cardon fron propshaft.' 'If you go the d2 centre you will need to unboplt your diff flange and swap it over.'

What do you guys think?
