Hi Richard, thanks for the diagram, I couldn't find that one until this afternoon. I copied yours and replied to Rimmer's as it gave the most obvious view of the parts. I am a bit surprised that Emily [Rimmers] didn't find this diagram herself seeing as she works for Rimmer's and deals with Landrover.
The one pity that I have is that the LRCat doesn't have pictures of the parts. I did notice that the listing for the handles does show American [LHD] models and, separately, American/Canadian/EU descriptions, from which I am pretty sure I have used the correct side for replacement.
The big plus was that the diagram that you posted showed which way the hook is positioned, thereby determining which side is which. It is unfortunate that LRCat didn't apply a different number on the diagram for the two sides, although looking again at the diagram there are three listings under the diagram.
Anyway, many thanks for your help.
