1999 XK8 Convertible. on the drivers side of the engine room there is a fuse box about half way the distance to the front. It is attached by some sort of "clips." That said, the recent addition to the family came with a cover for this box that is cracked beyond any repair, exposing most of the innards, which I don't believe is a good thing. Is there a part number for just the lid? Or are there sources of auto wrecking yards that might have such a small, but nevertheless important item?

 

Coventry West has Parts Cars and should be able to supply the Cover.

Don't forget to try eBay. Several fuse box lids for XK8s on there now. Didn't check which ones, but looks like several different ones are available.
