I just wanted to follow up in case anyone else is thinking of ordering these from Bimmian (or anyone else):

They did not fit the body. The tabs stuck out too far on the one side and the metal on the other. I had to cut them up with a hacksaw and peel all the weather stripping off just to get them to fit in the hole in the body. At this point they don't fall out but they don't sit flush either; I may just buy some bulbs and put the original units back in.
