Did you decide on what to do with the toe links and brake calipers? Who is making your new drive shaft? I need to get a couple of more made up, and I wasn't happy with the last guy I used. Now, you'll be able to dyno it when your done and see how much power you gain at the rear wheels. Let me know! Thanks.
FYI, you may need a custom brake line to go from the master cyl. to the rear "T". Mine was barely long enough, and you extended the rear wheelbase by 6", correct? I moved mine 4 1/2", but I did widen it by 11". You may want to order in advance if you do.
