Make it handle

[Coupeguy2001]

Hey Rob,
I HAVE BEEN LISTENING. now I am trying to turn faster.
Here's some of the things I heard you talk about, and am working towards the goal.
Just want to ask a couple simple questions,

57 Chevy truck, Kimbridge front frame stub that uses all G body suspension.
I used tubular upper control arms that have 6* of extra caster built in, tall ball joint mod, QA1 coilovers, 550 springs, 1 1/8 front sway bar,

The engine is moved back 2 inches and down 2 inches. Brakes are standard G body discs, with a hydroboost.

rear is from a 72 chevy truck with 3 inch dropped springs, and I made new shackles that are 1 1/2 inch longer and thicker than factory shackles,
and I have your 42 inch long adjustable traction bars in the back.

The tires are 255/50/17, Nittos, and are 11 inches wide, all 4 are the same. 27 inch tall. tread wear 300
I could go 245/45/17 on the front, but without a c notch, the rake would be too much, sticking the rear up too high.
I am limited in rear tire size due to the rear fender inside widths only being 12 inches, and I didn't want to tub the bed.

total drop is 5 1/2 inches in the front, and 4 1/2 inches in the back. If I c notch the frame a couple inches, I can get another inch in the back.

I know I have to move the gas tank, just didn't do it yet

Here's the questions:
with leaf springs and traction bars in the back, what diameter sway bar is needed? would I need a 1 inch rear sway bar? it seems to ride the rails pretty good and would a panhard bar help?

Question number two.
Would it be better to load the traction bars neutral or push the rear away from the transmission a bit?
It seems to stop clutch chatter when they are tensioned. I know the rear doesn't move very much now.
Should it?

As an oh by the way, I have some beefy rancho shocks for the front of the truck when it had the straight axle. would using these on the rear help cornering?
It would probably ride like a truck if I did! Hah! but the mounts are the same, and since it is lowered so much, they probably would fit.
Think of them as individual sway bars LOL
Thanks in advance for your reply
