You can get away with your stock shocks if you swap your spring pads to the opposite side. It is a way to stay on the cheap with your SPOA build. With your brake lines you can cheat and move them outside the mount on the frame and use a zip tie to keep them from floating around, but longer ones are recommended. This said, you should save up and fix the steering like Bash mentioned. One half of the Sky setup works perfect, but you can bend up your cross bar if your not careful. I ran a stock bar at Johnson Valley (To lazy to put the heavy duty one on during an axle swap) and it has a big old frowny face on it now. Even rubs on the springs.
If you are careful you can actually do a SPOA by cutting off your existing pads and re-welding them onto the top of the axle. I would spend the extra 100 though and buy the
Rocky-Road Spring pads as they make it a lot easier to put things together.
I originally ran 33" tires with a standard SPOA with some fender trimming in the rear and some work with a hammer in the front. Stock shocks and brake lines. For the rust problems on the rear, we actually cut out the rusty part of the fender and welded in a new inner fender. It added about 2" of clearance in the rear.

Of course, now I have a RUF setup with folding front shackles and F-250 shocks on the front end in order to get rid of the jack hammer ride, but the rear is still a standard SOA.
