You will want to find a wrecked donor car to do the swap, finding parts on their own will get fustrating and expensive.
I never done it, but if you want to do a true full conversion you'll need the 8.8 rear, quad shocks and brackets, chassis fuel lines, front spindles/rotors, V8 steering rack, exhaust/hangers, and engine/tranny/cpu related suff.
I'm sure there's a lot of misc stuff that I'm forgetting like the V8 tach, nuts/bolts, shocks/springs and ect, thats why you'll want a donor. There are a couple guys on here that are doing it right now, maybe they'll chime in.
