There are quite a few different lower arms for Mk3/3.5. As Oranoco says genuine Ford is best as patern parts barely last a year before needing replacement.

If you can cope with it you can replace the bushes with Powerflex, I've just done this to my mates and my Trackcar. I also replaced the balljoints at the same time. Took a couple of hours tops.
