We do have all of the original sized fuses in stock, we just don't have them listed on the store yet. Call or e-mail us to order them. The barrel fuses are used in all z's and zx's up through 1980. They are the round glass fuses with metal ends. The 81and newer vehicles use what is called a spade fuse. It is a plastic housing that is color coded and has 2 metal tabs sticking out of it.
