Thanks for putting Hunter's ute in context, jgsheehan: it was light in comparison to its competition. For example, Jim said the Americans were increasing suspension travel with stacked coil-spring packs which were heavy and in his assessment "agricultural". His solution was torsion bars, which were much simpler, much lighter and provided all the suspension travel needed. Also, regarding the extent of modifications, Class 6 was for mass-production-based cars - with the emphasis on "based". Things like original chassis rails, external bodywork etc had to be retained but there were endless freedoms beyond that. Check out one of Jim's main rivals at Baja that year. Larry Schwacofer's racer was loosely based on a '55 Chev - but that's about all!
