Good looking truck.   Can you give us some details on how you did it?  Is the rear axle shortened to fit the wider wheels under the wheel wells?   Was the turning of the front wheels changed to fit the wider wheels?   What about rear axle ratio?  I know one way to change rear axle ratio is to get a carrier fron a 520 J-13 truck, I believe it is a bolt in job.

Did you ever figure out how to crank down the torsion bars in the front?

It is so simple to lower this truck it is crazy.

Just find the back end the torsion bar where it attaches to a crossmember.

There are two nuts, one is a lock nut and the adjustment nut.

Loosen the lock nut, and turn the adjustment nut which ever way you want, up or down.

Each full turn of the nut is 3.5 mm or .138 in. up or down .

Tighten up the lock nut.

You will want to lift the front of the car up on stands and have a jack ready to help set the height of the suspension and take off tension.

It is realy amazing how much room in all directions there is in the wheel wells for bigger rims, plus remember, the stock wheels and tires I took off my truck were 26" in diameter overall, the 18" Armada rims with the 265/18 35 came in at 24" in diameter.

...You mean "How low can you go"?

I don't know, but as you crank it down you lose more and more spring rate, control, ride quality etc. I would just experiment, cause once you figure out how to do it , it is quick.
