Lloyd Hutchinson, in a 1275cc Mini- Cooper S and Martin Freestone in a Ford Escort Mk.1, head the post-historics and are seeded two and three on the stages, behind Nutt.
Ford Escort RS drivers John Moynihan, Tom Randles, Greg McCormack and Cathal Rogers lead off the classic cars, in front of Kieran O'Neill in an Opel Kadett GT/E and Philip Shaw in another Escort RS.
Austin McHale and Brian Murphy, in the Toyota Ireland Corolla WRC, compete in the weekend's 46th Rallye du Var in southern France.
