The listed collar for the IS version is the 'A II W' and the one for the non-IS is 'A II B'…I have no idea if they are interchangeable but they are listed as separate collars on the Canon USA site.
The Canon Tripod Mount Ring A-2 is the tripod collar for the EF 70-200mm f/4L (both IS and non-IS versions)
Apparently they are the same. I actually have the black version for the 200/2.8, but it works on my 70-200 non IS so it should work on the IS version as well. Thanks for the replies.

The "W" stands for white, and "B" is for black... other than the paint colour, those two collars are identical.
