I thought I should follow up with an update. After finaly getting the 40 running, it made its first wheeling trip this past weekend.
The truck now has scout power steering with the 4x4 labs hy-steer. SOA, sm420, lock-rites front and rear, longfield super 30 set, and 4-wheel disc brakes. 36" TSL's on the rear and 35" TSL radials on the front(running what I got till a decision is made on what to buy).
After a great day of wheling at the Badlands I am very happy with the whole set up. The power steering made a HUGE improvment to the rig. Arms and shoulders felt much better at the end of the day. It was extremly noticable going down steep hills under brakeing, and in the rocks. I only once noticed the locker causing any dificulty in the steering and just letting off the gas for a sec. cured that issue. I do not have a cooler on the steering at this time, but did not notice this to be an issue. The only complaint I have is I seem to have lost a lot of my turning radius. It really seems worse to the right. I am running the 4x4 labs 1" drop pitman arm that is about 6" long. Nothing I can't live with but it seemed to better before.
The SOA in the front is more tippy feeling on the road, but never made me feel unstable on the trails. My one change is my shackels, I currently have extended shackels that have been on the truck since I bought it(at least 4" or more bolt to bolt), and plan to change to stock length soon just to lower the truck some. It just looks too tall. I have 10" clearance from tires to fender in the rear and 14" in the front. Tube fenders in the front and rears cut all the way up to inner fender in the rear. Plus it is about 7'1.5" tall and the garage door opening is only 7' ask me how I know.
The extended wheelbase did seem to be helpfull in some climbs around the quarry, but all in all not noticable.
Thanks to all for the info and help along the way, this truck is by NO means done so more guidance will be needed in the future.
