99 s80 Brake Boost w/o DSTC
 

Hi,
Would anyone be able to tell me if a Brake Booster from an '04 s80 w/DSTC,2.5 T fit my car and would it work either way. I have a '99 s80 n/a w/stc only. Would I be able to install DSTC? Or did I make the amateur bad move???? I have a feeling I will be selling this part so if anyone is interested let me know, please.

Tanx all,
