You need a box from a sports car with a similar screen confuguration such as MGB or TR. Land Rover might also work.

One example here: https://www.mgocspares.co.uk/produc...later-square-8-sided-nut-type?nodePath=1

Note also that the angled rubber sleeves do also vary......MGB and GT were different boxes and sleeves.

There may be a part number stamped on the casing.
