ok, so it's only got a 7" diff. that won't last long or be fun to drive.
what estate model is it? has it got self levelling suspension? if not, and you manage to get lower uprated ones, i would have the originals off you.
spax do a kit of dampers and lowering springs for an estate

don't know if they'll do the springs only though, although they do the rear dampers only

so only 7 inch diff in the back
its been fine for 5 years now it just needed a rewiring as the original person done it just chucked it together and we didnt realise how bad it was untl i removed the dash to do some work

a normal sierra back axle will not fit
the shock and spring mountings are totally different
it would mean that the top rear strust out of a sierra being welded in
so looks like its gona have to be a lowering kit for a sierra
which is a shame

not sure if its cossie suspension or what

my shocks are std ford non self levelling, and the springs are standard from a self levelling 4x4 2.9i ghia
but as you can see from these pictures of when i drove home from germany with a full load, the springs are quite soft
i'm looking to get some more or less standard ride height springs to keep good camber angles, but very stiff for drifting once i've welded my diff up

What specs the motor in yours nick? gonna keep mine at a hopefully reliable stg 3 seeing as it will be my daily drive, cant wait to finally get it sorted, trying to get it booked in for simple setup and check over before I can give it some grief however is proving frustratingly difficult

Matt J only stg 2 mate, t3 and greens with 4x4 intercooler.
mick done that already mate, but could maybe go to the thickest ones. will be at a berks meet, though not the one next week. do you go regularly, haven't met you there?

the springs you want are the ones that power enginering did that were made by chassis dynamics
i've got a set on mine and it sits perfectly, even with loads of wieght in the back
and the spax shocks are crap (allegedly)
i got a set of koni adjustables on the rear of mine (again from power) and it's just perfect
now for the bad news, koni say they have never made any adjustable shocks for a sierra estate so no luck there
also, you need to make sure you get the right ones for your car as there are 2 different sets of fitments, and one won't fit the other because the wishbones have the holes in different places

dojj
good information there the differences are in the hole position in the semi trailing arm so that self levelling and non can't be mixed up. but i took non self levelling dampers and modified them to fit my semi trailing arms from my self levelling model and they're mismatched to the too soft springs 
i'll have to see if chassis dynamics still do the springs, not too bothered about dampers.

there are 2 different sorts of suspension mounts
the ones that are close together and the ones that are further apart
all the ones that i've seen (from the likes of spax etc) are for the smaller slots, and it's not just a case of opening up the hole in the wishbones because you need to space the holes out too
there is about half an inch worth of difference in the holes and seeing as there are captive nuts behind you can't really move them over a smidgen either so what you need to do is measure the space between the hole centres in the bottom of the wishbone where the strut locates
the second problem is the spring rates, they are higher than normal sierras as there is more load in the back of the estate, thats why they sit higher up too as standard (although the extra bit of body wieght tends to lower them to the same height) but if you put normal sierra springs on the back, uprated or not, they won't have the right poundage to give you both the look and the handling you are after
the self levveling problem is easy enough to solve, you just bin them but then you lose the ability to put 120kgs of garden roller on one side and still drive home with level headlights

on mine, i haven't touched the holes and nuts on the trailing arms. i enlarged the holes in the damper bar and had to grind down the bar a bit to make them fit.
the problem with binning the self levelling dampers (that cost a hell of a lot to replace
) is that the springs are then too soft as the dampers are no longer supporting any load that you might put in (or the weight transfer under acceleration) which means you get ridiculous wheel angles.
