OMG i just realized Ive have my info backwards. Internal EGR for the GT40 = passages to mount EGR externally on TB spacer.
Their "External" EGR uses a line from the manifold.
BTW the explorer doesnt use the ACT sensor like the fox uses, which is located on the #5 runner on the lower intake. The spot is there on the explorer intake but not drilled/tapped. can do that or move it around by the TB but upstream.
