if a 50 cent piece will cover the crack, you can have them repaired, usually fairly cheap. Most insurance companies will waive your deductible for a repair instead of a replace as well, since some cars can have a very expensive windshield.
However, I think the Ranger's windshield is pretty cheap to replace, less than 200 bucks. that being said, the last time that I had a chip/ small crack repaired, I think it cost me 70 bucks, but that was back in the early 2000's.
