100mm hub to 108mm on 83 CGT, what do I need?

[George Selby]

I just discovered that one of my wheels is bent, and in yesterday's 
excursion to the junkyard, there is a 85 4k with complete suspension, hubs, 
brakes, and the stock Audi wheels I happen to like (it also has the clutch 
fork I need!)

So what all should I take from the donor vehicle to convert the hubs all 
the way around to 4x108?  Naturally I'll swap the brakes, too.
