There are different size tools. I have one I've used years ago on my other cars that would not fit into my bird. I borrowed a set from a friend and it fit without a problem.
If you are going to go the lower arm route, you have to take out the bolts holding the lower arm onto the subframe, but leave the spindle on. It's a pain getting the arm re-aligned to install, but I've done it and I'm not an expert by any means.
