Cylinder head spanner remanufacture

[Ronald G. Stephenson]

Gentlemen: The is a box wrench, and they have been manufactured since the earliest days of automobiles. The common name is a 'start wrench' and as the name implies, it is used to reach that top-most bolt holding in so many starters. They usually come in two sizes that fits most starters. As to remanufacture, the process is called CNC machining, and once the program is written, you may pop out as many replicas as you care to produce. You may even have them engraved, blackened, hardened and the rest. One 'original' will do, and the rest is simple economics.
