It’s not just the windshield that is different, look at the door and door handle and you can tell that is the new cab.
Most definitely. I don’t care for what they did to the w990. They could have kept the 900, took the cans off, shaved the lights and it would have been more efficient. They could have called it the W900E and leave the W900L and B the way they are.
Without seeing one, I’m guessing the breathers will be somewhat oval similar to the ones that were offered for the 9900 IH back in the day to give the appearance of a 15” breather from the side.
