The 89 Shelby Dakota had no mech fan, too tight to fit. I would make sure the fans are blowing the correct direction. A piece of paper hung in front pof each one in turn will easily verify that. Temp creeping up at a stop tends to verify an airflow problem. I don't know how sensitive the Dak is to air dam presence, some vehicles will not properly cool if the air dam below the radiator support is missing.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
