OK, first off, there are two sizes. The smaller ones are the only ones that work in the lexan. Second, the bearings go on the shafts first. Note that they go on flanges down (if the lexan is on the bottom). Make sure the plate is put on with the large hole over the large bearing (which should be on the longer shaft).
