I think you have to mill those spacers down the are on either side of the bearings.

The R a-arms are a 1/16th or so wider. You just need to save them down a little on each side. You can use all the R hardware too.

Are they stock or aftermarket? If you want me to go out and measure it I will, but wn't be able to get back to you till tommorw. I have an R and EX sitting in the garage. I am possitive, if you take the bushings off the R a-arms and cut them down they will fit. You will also have to cut down the sleave taht goes in the a-arms joint. I am sure it is only a 1/16 or so difference.
