Hy UncleRichie, welcome, that year truck did not use a front wheel seal as we know it today, they used a large felt "washer" encased in two pieces of metal. You may be able to find new felts if you need them, or as someone else has already pointed out, you could take the metal felt retaining pieces to a bearing and seal supply place and have them order seals based on their dimensions. You would have to take them the dimension of the surface that the felt seals to on the spindle, so they know what the bore of the seal should be, hope that helps.
