I also seem to recall seeing the original dampening pad as well. It wasn’t as thick as Dynamat!
I’m guessing Jaguar applied the deadening pad earlier in the assembly process - maybe even before they attached the door skin, but for sure before they attached the water deflectors and perhaps the window mechanisms.
If the deflectors are in place I can’t see how one would get a decent sized dampening pad in place, in the right location.

You don’t need to put in a single large pad. Multiple smaller pieces abutting one another will work just as well. When you run the roller over them they will all squish into one larger pad.
How would one get a roller in there with the deflectors in place? 
I don’t know if you can get a roller in there even if you remove the deflectors, because the winder mechanism takes up a lot of space even with the window up. And the size of the aperture means you can’t roll the roller very far upwards.
But if others have managed it, I have to defer to that…
Dave
Just to make sure, by deflectors you mean the plastic water shield?
I had room to get mine in there with the window rolled up fully. It’s not as quick or easy as placing the stuff on a flat exposed surface, but it’s not really difficult.
Ah, no, it’s those black sheetmetal plates riveted over the lower door apertures in the photo I posted. From past threads I got the impression those plates are not common - I seem to recall someone saying they’d never seen a picture of them before.

Might be me. My 3.8 doesn’t have those or holes for mounting them. I guess they must have added them at some point, for some reason.
Mine didn’t have them and there is no evidence the car ever had them. My old 2+2 didn’t either.
Mine did: they got left out, upon reassembly. Sent them in the boot, when I sold it.
I notice not everyone puts the matting over the wheel wells or on the driver/passenger exit areas.
Also getting good input on covering the wires in the sills with different items mentioned: string cardboard or Masonite or tar paper.
Would you all post up pics of how you dealt with the sill/wire area please?
Thank you.
I ran the insulation up a short ways at the sill stopping short of the wires.
This made the transition a bit smoother as the foam (then vinyl) went over the wires (there is a slight indentation in the sill for the wires).
Before covering the sills I made very sure all wires were working and sound. I also added a cable for a rear camera - haven’t installed it yet, just ordered and laid in a cable while everything was open.
