Booo on headers.
JUST SAY NO to headers. Unless I was building something fast, that I was trying to get every bit of horsepower out of, I would go with ramhorn exhaust manifolds.
Headers can be so s***ty. Just last week we were working on my buddy's dads 67 Chevelle. It took forever to get the spark plugs out because of the headers. Then we changed the starter which took forever because of the headers.
The starter had to be one of the small/high torque starters that you can index and change position of the motor, because of the headers.
Then we burned up a spark plug boot, because of the headers.
Not to mention they blow header gaskets, yada yada yada.
Get ramhorn exhaust manifolds.

Got rocks, may I ask you a question? 
I'm going to do on my FJ a four link more or less like the one you built on yours, but I still have some doubts.
Firts of all: squat and antisquat! Did you calculate them? A lot of people says that is very imprtant to calculate the squat, but I must do some modifies to my project if I consider that, so I want to be sure that's a REALLY important thing to keep on mind.
Another thing: is yours a kit or did you built everything on your own (links, coil supports etc.)?
Please tell me something, everything will be so intersting for me since I'm going to start that work but I'm still too confused!

Ah, some more pics will be VERY VERY VERY welcome!!!

and some more for the kidsin the bottom picture in post #69 you need to rotate the lower shock brackets 90deg so the shock eye is parrallell to the axle, not perpinducular to it.. when the axle articulates the shock will not rotate at the bushing correctly the way you have it now.. this will destroy the shock bushing or break the eye off the end of the shock...
one other thing is try to angle the shocks "in" a little at the top.. this will allow them to actually "work" under articulation... having them straight up and down only allows them to "swing" side to side when the axle articulates, not compress/extend per se'

Are your rear upper coil buckets just located on the bottom of the frame rails? Or inside? Have a good close up pic?
I know this is too late, I would have done a 3 link front with a track bar. A lot of aftermarket companies are doing so on TJ's. They work and handle excellent.

inside i am thinking of moving them to under the frame here is a pic the way they set right now and as far as a 3 link in the front if you have some good info i would like to see it. my fj will be my dd so would like it to drive good no the road
Thanks for that pic. Why are you moving them under the frame rails? Clearance for the shocks?
What info would you like to see about the three link?

[FONT=Arial, Helvetica, sans-serif]System C:[/FONT]
[FONT=Arial, Helvetica, sans-serif]System C is a long arm system that uses an independent 3 link front end with track bar and a triangulated 4 link rear end.[/FONT]
[FONT=Arial, Helvetica, sans-serif]Benefits: [/FONT]
[FONT=Arial, Helvetica, sans-serif]1) Very smooth highway ride quality when accompanied by appropriate springs and shocks.[/FONT]
[FONT=Arial, Helvetica, sans-serif]2) Excellent for full axle droop conditions and high articulation conditions on the front and the back.[/FONT]
[FONT=Arial, Helvetica, sans-serif]3) The only front and rear end design with no natural binding points or premature wear points if implemented properly.[/FONT]
[FONT=Arial, Helvetica, sans-serif]4) The front end can articulate as much if not more than the back end which provides excellent vehicle balance.[/FONT]
[FONT=Arial, Helvetica, sans-serif]5) This type of system either the front end or the back end is found in the highest levels of rock crawling.[/FONT]
[FONT=Arial, Helvetica, sans-serif]Draw Backs: [/FONT]
[FONT=Arial, Helvetica, sans-serif]1) For the front end; the torque plain is only attached by 3 points.[/FONT]
[FONT=Arial, Helvetica, sans-serif]2) For the rear end; the rear end is over constrained, but a properly implemented triangulated 4 link design functions like a tri-link design.[/FONT]
[FONT=Arial, Helvetica, sans-serif]3) The front axle side shifts through articulation because of the effects of the track bar.[/FONT]
[FONT=Arial, Helvetica, sans-serif]4) May require exhaust modifications. [/FONT]

Any updates I am in the procurement process of this same build Thanks
Just now checkin out your build. Why did you not put coils in the front? Here is what I did. 14" Kings
