Andrew,
FYI - Porsche Classic is having them produced again, so you can order a new one with the correct dog-leg 5-speed pattern from any P-dealer & other Porsche parts sellers, such as Sierra Madre, Auto Atlanta, Stoddard's, Pelican, Einmalig, etc. Suncoast & Sunset Porsche dealers' online parts websites sell them at a discount online too.
Otherwise, nice used on here, 914club.com, TheSamba, evil-bay, etc. have them come up all the time.
Cheers!
Tom
