I am in the process of that swap over. It is a easy switch if you are also changing to the Comstar wheels. Otherwise, it takes a bit of effort. Keep in mind that you will also need the calipers and caliper mounts from the F model. I won't be able to report on my progress for some time yet - I am also in the process of redoing my work area in the garage. In the meantime, there are quite a few posts in the forum regarding the dual disc set up; the search feature can find those for you.
