I'd say count your blessings, the doors you have are actually more difficult to find and, at least when I was looking, more expensive (I have not seen them in repro. market, but that does not mean they can't be found). You can probably sell your early model doors and buy new "correct" doors with the full lower amber plastic and break even...at worst. Personally, though, I like the older units or, better yet, the euro lamps.
Best,
