Yes. On a 97 with 78K miles it is tires/wheels/shocks/ball joints/alignment most likely and any of these things could potentially cause shimmy at speed. Swap wheels and it goes away? Tires or wheels are your problem. Doesn't go away? Shocks, alignment or ball joints are your problem.
Simply eliminate the possibilities one by one until your cause presents itself.
