I also had on that was stolen from my D90 during shipping and I bought one from Falcon and it was fine. It was clear coated but looked good to my eye. I did not try stamping the number into it because I did not want to take the chance of breaking it so I had it engraved. Not quite exactly like the original but it worked well enough.
Proud restorer and former owner of '94 NAS D90 #590- back in the hands of its original owners.
And now happy owner of a 1988 Swiss-Market D90 Station Wagon.
