It covers mainly the 240Z, but since the 260-280 are so similar, almost everything applies to them, too. Does not cover the ZX, although again, almost everything in the book can be applied to a ZX restoration. It's an excellent book for anyone wanting to really fix an old Z from the ground up. Another good one is Bill Reagan's book about restoring the 240Z used to model the Franklin Mint Z. Again, focused on the 240, but methods and procedures apply to all Z cars.
