I'm no expert on that vintage truck but the above given prices sound quite high to me.

For a reasonable guess at value compare prices for similar trucks that do sell on ebay over a few weeks or months. Try to judge and compare condition of those and yours as that is a major factor in the value. Location also plays a part in the value.
