Why not just buy them from Porsche.

The front control arm bushes are available - tricky to fit but work well and worth the effort.

Rear Spring Plate Bushes are also available as are Trailing Arm Bushes.

The only bush that is NLA is the Front Camber Plate Bush.

Many SWB cars have been fitted with the later and incorrect camber plates which will restrict both caster and camber adjustment.

In other cases the correct steel plates have been used and fitted with Koni Shock Absorber Bushes. These parts will fit the camber plate but they doesn't locate correctly and have the wrong shape.

We have manufactured the correct design of bush in a 80 ShoreA High Density HNBR Material and they were used between 1965 and around May 1970then the inner wing profile of the shell was changed.

Hello Chris,

Many thanks for the steer on bushes, in ordering these bushes are they the same type / dimensions as 64-67 or 69-88? Or as many things 68 something else?

Thanks Rich

Front Control Arm Bushes - 914.341.422.00 The fit into the housings on the ends of the control arms and press into place. They have a much smaller ID than the end of the control arms and as you press them into place they stretch from around 35mm long to around 55mm long.

This stretch means that the rubber is held with significant radial compression which improves its static modulus and locates the arm very positively.

There is a URO manufactured slip fit rubber bust which is much, much less effective.

It is a PITA to fit these bushes and we have made a hydraulic powered fixture to do the job more easily

Spring Plate Bushes 901.331.105.00 x 4 these were used as the outer bushes on pre 68 cars but work as inner and outer on a 68 shell. I would glue them onto the arm using 3M Scotchweld adhesive.
