Buying a new diff...
Hi all, Im just after some advice on getting a replacement diff from the wreckers- what should I be looking for/what should i expect? Some wreckers Ive looked at have diffs sitting outside on racks, and i dont know if this is a good thing. (Keeping in mind that I have no idea what Im talking about): My gf's dad, who is going to swap over the diffs said I should buy a diff that has the axels attatched (or something), and isn't 'full of crap' on the 'inside', preferably one that the wreckers have to take out of a car, as opposed to one thats just been sitting there for ages.
Any advice on what to look for mechanically/price wise would be greatly appreciated. Also its just an ED 3.08 diff im after.
