Suspension leans

Need help on this one.
On my 69 I have VBP front A arms and mono leaf spring kit. and full rear mono leaf kit.
Im trying to get the body height correct from side to side.
I found that the car leans to the drivers side, front and rear.
The drivers side front suspension bumper is touching while the passenger side is 1/2 inch away.
here is what I done so far.
1) The frame was checked and is within specs.
2) All mono leaf spring adjuster bolts are at the same length,,(threads showing under adjustment nuts)
3) disconnected front and rear sway bars.
Im lost here please help

Mine was leaning too. Turned out to be the rubber pad for the center of the rear mono spring was coming apart. I replaced it and the car leveled out.

ADDED SOME PICS, Do you see anything wrong, look at the front snubber.
cool9 What rubber pad in the center are you talking about.

With the dual mount VP&B suspension there is no positive centering of the spring, even an 1/8 inch off center will change spring rate side to side. I do HPDEs with the 6t8. I have different spring rate settings in 3 corners and use the adjuster bolts set for ride height. They are all different settings. By the picts your spring rates are all the same [can only see 3]. If you scale the car you'll see different weight at all four corners, the VP suspension is more sensitive to weight per corner, but it has adjustments for tuning. I don't know how perfectly the springs are made, but a side to side movement will increase spring rate on one side and decrease on the other. By changing of the location of the allen spring rate bolts you'll be able adjust rate per corner. Remember the driver side has battery, steering, braking and you. To tune yours, lets say you back off spring rate on passenger side, now it sits same as the driver side, then you crank up the spring bolts for your ride height. You should end up with a good gap on those rubber bushings. It's a trial and error process. Maybe this helped. T

Thanks Terry.
I thought that the adjustment bolts had to be somewhat the same length. I will try that but don't want it to look stupid.
I am running a supercharger also so that's adds weight. maybe I should call VBP and tell them I have a big block and blower to see what they say.

I'm also putting a charger on mine, GREAT minds think alike. Who was it that said 'no questions are dumb questions'.

I ask questions all the time. What kind of blower system you running? I'm installing a Vortec V-1 on a SBC trying to keep it under the hood. The VP&B systems sure make are cars handle, don't they? I was wondering why the pump [A1000], same one for me. T

Just for grins.....is your wheel alignment close to what it should be? I would think that camber settings being different MIGHT have a little bearing on your ride heights.
