I have been through piles of 435's, and I have never seen a close ratio dodge one. Not saying they didn't make them, but they aren't very common. I have seen some 445's, that are fully synchroed and have a 4.56 first gear. Most 435's only have one PTO cover, all 445's have 2, as well as some 435's. I can't help you ID a close ratio 435 since I have never seen one.
