Yup, even though there's 4 spring posts and 4 possible ways to install spring/pressure plate, only
TWO of orientations will work. Look carefully and you'll see that teeth next to some posts are raised and some are lowered. You can't just put in pressure-plate any which way. Have to line up
dimple marks. Otherwise springs won't be able to push inwards on pressure-plate and compress stack.
