Yes. You can safely assume that all auto paint made before 1990 or so has some lead in it. You can use one of the test sticks you find at Home Depot to make sure, but chances are you do. You need to collect the dust and make sure your children do not inhale or ingest it. If your garage is attached to your house, find somewhere else to strip the paint, and don't wash your clothes in the same machine that you use to wash theirs. Lead is far more hazardous to children than adults.
