I am assuming that I need a box spanner to get the nuts off the outer casing, that being the case what size spanner do I need ?

Regards Rich

You need a 1/4 BS (3/16W) spanner, a 3/8 inch drive socket is better than a box spanner.

Auto-jumbles and boot sales are your friend. You will need a set of BSW sockets. These sell for next to nothing now as very few people have anything they fit.
