12/20 - Well my truck would not stay level after turning a corner after I installed the Coilovers, so I'm going to try Sway bars on the front and rear of my truck.
Problem is, nobody sells a kit made for an 84 Toyota with Link and Coilover suspension, so I found a Universal kit from AntiRock that would have to try and make it fit somehow.
I had a pretty good idea of how I was going to make the Rear fit but the Front was going to be really tricky with a lot of stuff in the way of it and it took a lot of thinking.
First I had to relocate Coilover Reservoirs out of the way, so I moved them to the other side of the shock bracket which was actually a big pain but it I got it done.
Next was moving the lower Coilover mounts back towards the outside (to gain clearance between the coilover and frame) again but I had to move it up so the springs would miss the Steering arms.
Next was locating the torsion bar, front to back, side to side while trying to envision the side arms rotating up and down, and missing the steering pitman arm turning side to side all while the entire axle moving left and right as it travels up and down, and I only had about an inch of play between the Coilover spring and its bracket on the frame for the sway bar arms to fit. :-) This took a few days of thinking about the pro and cons of a couple different locations.
I finally came to the conclusion of what I was going to do and it involved slightly modifying a lot of stuff.
I had to flip the arms over and cut 3/4" off of the torsion bar on each side to get the arms as close to the frame as possible.
But that was still not enough and I had to bend the bars themselves to get even closer to the frame. Each with their own unique bend.
Also I had to notch one arm to miss the steering Pitman arm.
I welded a strengthener piece to hopefully keep its strength.
Next was actually mounting the Torsion bar. I had to get the torsion bar as close the underside of the frame as possible in order to clear the Steering Pitman arm, so every 1/8" was counting.
I notched the tubing that holds the torsion bar in place so that the torsion bar could actually touch the frame and gain about 3/8".
Then I cutout the center section because I didn't need it and allowed a little more clearance around the engine.
Next added the torsion bar in place
I had to also grind the Pitman arm some to get more clearance.
Next was sticking the arms on and doing some grinding on the coilover frame brackets to clear the swing of the arms.
Then found a good place to mount the connecting link to the axle.
It close but it all works! Even when cycling through the suspension travel.
And this side I had leave about a 1" space because as the axles drops, it moves towards the drivers side (right side of pic) and pulls the Coilover with it.
Now on to the back!
I had to start by cutting the tail pipe off and rewelding it shorter.
That gave me space to weld the cross-tubing to the frame with a couple of custom brackets.
Then find a place for the lower brackets and weld them on.
And finally connect it all up.
And that did the trick!! The truck can now go around corners without tipping over and straightens itself out! It also still has a lot flex.
