If I remember right, there are 2 different shift towers. By changing the height of the pivot ball it changes the throw of the shifter. Then change the length of the handle and stuff changes even more. A while back (couple of years?) I remember seeing a picture that had 2 different 435 shift covers.
It would make sense if the taller cover (short throw) was used on applications that had a very long shift handle. Long handle makes for long throw, counter with a faster ratio ball, normal throws for stuff like school busses.
Back when I had the 435 I cut the shifter just above the ball. Took out the first bend and about 8" of steel. Welded it back together. It was a great shifter. Shortish throws, cleared my leg and the stock T-handle transfer case shifter. Easy to reach al the gears. Only thing, the spring for the reverse was a little tough. Kinda had to toss it into the reverse gate instead of just a push. Needed a little lighter spring.
