I just spent a few hours reading this thread and wanted to say a couple of things. First, great build thread and fantastic fabricating skills! As far as the Scout part of it goes, I pulled the front leaf spring packs off a V8 Traveler about six months ago in a local JY. The body was probably 90% there, appears it had a small impact on the drivers side corner but the motor was trashed so the owner junked it. Unfortunately, it went to the crusher when they were through with it. A part of it lives on in my XJ rear suspension.
As far a the wind deflector for the rack, I have a smaller rack which was creating a lot of resistence at highway speeds and even a hum when it was windy out. I made a deflector out of sheet metal and installed it and it is 100% better and quiet now. Just saying.....
