to order parts.

Photo shows 522317, BSK1531, these do look like part numbers but aren't shown in any of my parts books.

The next numerical part number that is shown in: UK Series III June 1988 parts catalogue page 1H09, is part number 522318, description - housing assembly, being for speedo drive housing assembly.

REF; Land Rover Owner • View topic - Gearbox suffix ?

Suffix B, C & D main boxes will have some thick ribs on the outside right hand side against the transfer box, suffix D can also be found with the bolts holding the reverse gate to the selector rod end being 2 bolts on a horizontal alignment rather than a vertical alignment.
