Yes I had to enlarge the holes on my W123 300D... but you'll notice that it is only the lower - or inner bit of metal - that needs to be altered. I used a round file, but, other people have reported using a Dremmel...

After altering the hole don't forget to stick something like POR15 over the bare metal. (Stick some grease on it at the very least)
