Blake,
I don't know about the specific numbers you give but I'd bet they're right, since they are clearly for a W124 and the 300E uses the smallest bushings of any W124.

The numbers have changed most likely because the parts have been modified. When I redid mine, the new bushings had sort of a nylon-ish mesh on the inside diameter, unlike the originals, designed to keep them quieter longer.
