LIFETIME STEERING COUPLER
The last Steering Coupler your 911/912 will ever need; completely and totally fail-safe, fits '65 to '89 without modification.
For reasons understandable when our cars were new, the Porsche factory bought steering gear couplers of elastomeric 'discs' or 'tubes' with bonded metal fastening inserts. The metal parts tended to last forever while the elastomers failed, with the possibility of leaving scant or no connection between the steering wheel and the front wheels. It is axiomatic that any elastic elements fail long before any metal does.
This precision engineered steering coupler is guaranteed even if there is complete failure of the elastomers. Under that complete failure, the steering wheel would gain ~1" radial 'slack' at the rim and ~.03" axial movement. And you will remain entirely in control of your car.
