David,
Depending upon which Nishiki model you are inquiring about, my guess (...as in reasoned speculation based upon vague recollection) would be that KKT Top-Run pedals would be a good bet. For yet more vintage Nishiki related information, you may wish to revisit various contemporary road tests and reviews:
