i take it you are not going to have a donor car?

if it helps, my diff came from my donor which was a 1.8cvh sierra estate & its ratio is 3.92 with push in halfshafts .

I was thinking against a donor simply because i dont have the space to keep one whilst i strip it, although i realise this will proberly work out dearer in the long run,

if your planning on a car engine and a non race setup any sierra diff will do the job to be honest. if you look in the haynes manual for the sierra it says what diffs come with what engines.
