Just wish there was such an animal for the Disco 3, missing it and also
The Part Catalogue

A point of caution. As you have a 2004 model.

I have found that for later years sometimes the rave manual is not 100% up to date. It appears LR did not think some updates in the manual were needed. But most is fairly simple mistakes.

Also the parts catalogue above, again a very good resource but do verify your VIN number as again some of the part numbers do not match for later years. I usually take the part number , google it and see if it has been updated. Or even call one of the suppliers I prefer to use for verification.

Cheers
