[DeTomaso] Nickle plating on suspension arms

[GW]

Hydrogen embrittlement is more of an issue on high strength steel and 
fasteners. It's generally not an issue on mild steel.

The source of hydrogen embrittlement is actually the pickling and 
cleaning process before platting. If you are concerned and you bake it 
(or your platter bakes it) it has to be backed after the pickling.
