The 1970-78 Z cars use five of the 20 amp and nine of the 10 amp fuses. If you are having any electrical problems, fuses are an inexpensive place to start. We have had old fuses that have poor contact due to corrosion or loose ends that create electrical problems even though a basic test shows them to be good. Sold in packs of 5.
