Anyone know how much a set of sx trail chainstays cost from specialized?

Seem to have a crack in the chainstay unit on my 06 enduro s works, it’s a known problem :-(. Read up on mtbr that spesh send out sx trail chain stay units on warrantee as they fix the problem by being stronger. No warrantee on my frame so I’m buying a set by the look of it 🙁

Anyone know how much it is for a new set, and if spesh will offer crash replacement on 2nd hand frame?
