what parts will work?
Im looking for blonde wood furniture or black or olive polymer furniture
and an AK74 brake for this
anyone in NJ have the parts or know someone who can fit it all for me

I just pulled these off my NIB SAR-2 and replaced with a kit from RPB ($125 Krinkov kit: www.rpbusa.com/misc.html).

SAR-2 Extra set:
 How about $50 shipped for the stock set?

This is an AWESOME website for the SAR series, tells you how to do damn near everything! linx310.nothingbutguns.com/

As far as the AK74 brake, read either the site above or around the AK section of AR15.com and that should answer your questions.  There are MANY different ways to accomplish attachment of a AK74 brake, depends on how much '$$' and if you want to do it yourself.
