I sorta remember a post on here from a member saying that Zigs leaves out or replaces pieces that are included in the Total Cost Involved package. I would give the them a call first to confirm exactly what they include and that it is all complamentary to the pieces they replace. Yes thats what it was! Zigs gets pieces from T.C.I. (the one in context) but not the entire setup, and substitutes what pieces they can make inhouse to save on wholesale cost from T.C.I. Now this member stated the fitment was a problem, so I would verify this with Zigs before ordering. Cause I am writing this from memory wich is most surely been found faulty through legitimate claims by my old lady!
