Replacing Rare or No Longer Available Parts

Many times an item will go out of production as vehicles age. And frequently there are design flaws built into parts that were manufactured years or even decades ago. A good example is the "Shift Operating Spring" found in the 5 speed gearbox of the Porsche 928. The function of the part is to provide the centered feeling when the gear shift is at rest by applying pressure within the gear change mechanism. When the spring steel portion of this level fractures, the loose part falls into the gearset and causes quite abit of damage. Owners report failures of this item in as little as 5 years, and many consider it a maintainence item.
The design was changed several times, but the spring portion remains a concern among owners and is no longer available from the factory.

Perfex Manufacturing will overcome the design flaw and make the part available to support Porsche 928 Owners

Using modern materials and manufacturing process, this item will be brought to market at a reasonable price, saving countless manual transmissions that would not otherwise be serviceable.
