I haven't done Elijah but I did get some beta from Noddy a few years ago: there is a 50 foot traverse (left) missing in the Joe Friend guide. The trick is to find a traverse line that takes you across almost to the blunt arete R of Flight of the Phoenix above the first big line of overhangs and below the second. It goes a long way left from the point where Trouser tracks leaves it.
I believe the topo on p.25 of Mark Colyvan's Rock guide is reasonably accurate (allowing for the big dots and the fact that the 300m wall is 6 cm high in the photo!) Happy to send you a copy of the Rock guide if you can't get hold of an original.
