Which diff?

Well I think the way to go for me is the C-Clips way with thicker clips and shims. My car is only street driven and never sees a track.
My problem is however that I, for the time being, am living in France where American cars are an unknown thing. So finding a mechanic that understands a 12 bolt might be a difficult thing.
I do however have an old Ferrari mechanic which seems very meticulous and does prime work, I might let him have a go.
Does this job include the whole setup "ring and pinion" again?
If I want new stronger C-Clip axles, what should I look for? I do a lot of buying from Summit, so if it´s one of their product, that would be nice.

Thx for all the replies, nice to have all this knowledge available for us guys not living in the US.
