Sierra Uprights

The Ford Sierra upright can be modified to from a MacPherson Strut to an upright for an A-Arm setup.

The top ball joint is from a Ford Transit van, as per the book by Chris Gibb. The top ball joint is mounted in a custom made adapter.

The bottom ball joint is from an Austin Maxi. The taper on the uprights’ lower ball joint mount needs to be enlarged.

The track rod end is from the Sierra.

Note:The measurements are taken from the relative position of each ball joint to the centre of rotation and to the mount mounting surface of the brake disc.

The drawings show the steering arm horizontal. In practice this would give a negative castor angle and therefore it is recommended that the upright is rotated to the correct castor angle.
