I am replacing the EGR on my Taurus Wagon 1994. The part I bought from NAPA
does not come with the pipe that is on the back of the EGR. Its called a
back something I think. I have to take the old one off. However the bolt is
a torx and it is stripped. So I want to just grind it off and replace the
screw. However I cannot find the right size tapered machine screw. ( I have
the new part to try bolts on) Its very small. Can anyone tell me what size
this is so I can call places to find out if they have it.
