Hi Turboseven
A quick note on the suspension etc. The front axle beam uses a transverse leaf spring clamped to the chassis at its centre, with a short shackle link at each end. The axle is held in the fore-aft direction by "radius arms" which run back to a single ball-and-cup fixing. These arms also resist axle twist when braking. The shock absorber uses two arms and a set of round friction discs with a single central bolt.
The rear axle uses a pair of quarter elliptic leaf springs anchored into the ends of the chassis. The prop shaft ends ahead of the axle, drive then runs through a short shaft enclosed by a "torque tube" with a ball and socket mounting. This gives some additional location fore and aft. Again, friction dampers are used with one each side.
Steering is via a worm drive gearbox with a drop arm. This pushes and pulls on a fore-aft link tube which connects to a steering arm on the offside hub. The nearside hub connects to the offside via a sideways tube or track rod. The ends are threaded to set the toe-in. The steering is quite direct, not many turns lock-to-lock as these cars only weigh 600 kg.
Even when everything is reconditioned to remove wear, the handling still takes some familiarisation !
Many of the original Austin owners handbooks have been scanned and are available online. Here's an example: https://archive.a7ca.org/wp-content/uplo...7_1182.pdf
