Early models had the metal grill as a carry over from the Datto 1000.
Then they swapped to a plastic grill with a "D" in circular pod in the centre.
Later model utes (concurrent with the 120Y) had the plastic grill with the "D" logo in a
rectangular pod.

Personally, I think the plastic+rectangular D is butt ugly, the circualr D is okay and the metal
grill is best.

Windscren rubber can probably be made new for you by a windscreen rubber company.
Check the phone book.

Chromed plastic rear lights are a lost cause.
ALL second hand units should have peeled by now.
They charge a fortune to rechrome these things.
And new stock will not be easy to find and not cheap.
I recommend painting them.
Clever use of masking tape should get you a nice two tone finish.

Front light surronds are metal.
Clean em up and take them to the local chrome plating shop.
No worries.

New windscreen should be okay at your local windscreen replacement shop.
May take them some time to actually get it in stock.
May get lucky at a wrecking yard.
