As Dave said, the simple answer is try it.
Assuming they are bronze bushes which they should be on your car.
Make sure there is no harsh dirt embedded in the bushes and give them a good clean with degreasing fluid then try the king pins for fit.
If there is more than a few thou of clearance especially in the bottom bushes then change them but if all feels relatively "tight" they should be ok.
However, if you've got no detectable wear, I would have to ask when they were last done in mileage terms because that suggests they have been done recently (again in mileage terms) and that will give you a clue as to the answer as well.
