I have an ORD steering brace, and its awsome. If I ever get my junk running again, I'm seriously considering Kert's shackle flip out back. That thing looks awsome. I called his cell about a week ago and talked with him.
What kind of rig do you have? wheelbase does play a role, but since the shackle flip points your pinion up, you very well may not even need a shim. Crossover seems to be the most popular way to go for steering. You will have to get ahold of a 2wd steering box or at least the sector shaft from one of those boxes. If you're not concered with hardcore wheeling, or are on a budget (like me, lol)....you can just get a raised steering arm. I think you have to beat the crap out of the old steering arm to get it off. You will probably want to go with some Tough Country EZ ride front springs, or some BDS front springs, 4" lift springs that is. There is also an article about swapping 52's (stock rear springs from blazers and other trucks) onto the front, for about 4" of lift. That would take a little more skill to do than just some lift springs for the front. And you would have to go crossover, I think, if you did the 52 swap.
You will want to get extended brake lines, I think there is a part number or two floating around for some good lines from Napa.. do a search on that.
You will obviously want longer shocks. It is popular to use shocktowers from ford superduties on the front, so the shocks won't limit your flex. It is also popular to move the rear shock mounts inboard, but that takes some welding skills. Garbriels seem to be a popular choice, because they are cheap, decent shocks. I think Bilsteins supposedly are really high quality rideing shocks.
It all depends on what type of wheeling you plan to do. The sky is the limit as far as suspension goes. Stick around here a while and you'll hear about all kinda of suspension setups.
thanks,
