I need a set of rear freeze plugs for my 3.1L V6, I would like to get brass ones, all I can find on summit is ones for the 305 and the 350, do these also fit into the 3.1L And also do any auto parts stores stock freeze plugs that are something other then steel.

 

You should be able to go in to any decent parts store and tell them you want brass freeze plugs for your car and walk out the door with a set.
