Here's a pair of new Gearbox Mounts for the following models from Austin -

AUSTIN

Austin A50 Cambridge

(1954- 57)

Austin A55 Cambridge  (Mk1 & Mk2)

(1957- 61)

(Includes Saloon, Van & Pickup)

These are useful to reduce vibration or just to replace perished mounts.

If you have your gearbox out it is sensible to replace these mounts at the same time.
