85` pwr windows and locks in my 83?

If the power windows and door locks work perfectly that would be unusual for an old truck. There are lots of parts: door lock actuators, power window motors, switches, and harness/connectors, rubber door boot, regulators, etc. You should expect to replace some or most of these components over time, so I would factor that into the equation. If you start pricing these replacement components with GM OEM or Delco parts, then the cost of rehab on an old system might not make sense.
