I am in search of a part and I do not know the name or Part #. Can anyone help.
I am awaiting a parts catalog I have on order.
It is the metal part that bolts to the door to hold the front quarter glass as highlighted in RED in the attached picture.

 

Sanchez,

I'm not sure that part was sold separately, rather than as part of the door structure.

As mentioned, you can look at all the parts diagrams, part numbers and prices, freely available on Jaguar's parts website. See here for the relevant areas for pre-facelift XJS and the original 3.6 XJS parts diagrams:
