saph 2wd front coil overs fit fine on my standard 3 door sierra hubs, only problem is if your using the genuine 3 door cosworth alloys they wont fit properly and you will have to adjust the coilovers up a bit, but if you get some 3 door cosworth hubs it should fit fine
the rears will also fit but the rear inner wheel arch on the passengers side i think it was will need about 3mm bashing with a hammer to stop the springs rubbing and the mounting to the rear arms will need a few spacers either side of the coil over where it mounts in the bolt or just tighten the bolt to squash the mounting point which isnt ideal but will do

but the coilovers is a great upgrade mine handles like its on rails now and im not going to bother with a rear anti roll bar is it doesnt sway much atall with the coilovers anyway

ill try and find some piks for you so you can see tomorow
