Ride Height Problem??
 

My car is a 69S.At speed, it handles like crap.Front end feels light and jittery,steering wheel shakes. I've had it aligned and balanced several times but that doesn't seem to make any difference.
I think that as air gets under the front of the car,it handles poorly.
For example,it feels much different going downhill than it does going uphill. Front is 25.5 inches to fender lip.Rear is 24 inches to
quarter panel lip.Seems to me that the front is too high and rear is too low.Tires are 225/50 15 rear and 205/50 15 front.
So, can I leave the rear and lower the front ? Bump steer spacers? Immediate alignment? Am I on the right track?
Thanks in advance....

Early cars may be different, but I think, primarily the rear is too low. Bruce Anderson suggests 25.5 frt and 25 rr to be the correct height for our cars. I think your torsion bars have likely sagged. Not sure if it would be best to just raise the rear or spring for new torsion bars.

Ideally, you should lower the front and raise the rear. But for now, it is both easiest and best to lower the front to about 24 1/2" with a full tank of fuel.
The rear height is very difficult to set on a pre-'77 car, and will usually result in improper corner-balance problems when done by the inexperienced.

You'll need to get it aligned afterwards, as the lowering will affect the camber and toe settings.

Using fender openings is very deceptive since the front fenders are cut 2" higher than the rear, so having the front and rears at nearly the same height will result in the front abnormally low.

There may be a reason the factory does not use fender openings as points of reference but specs torsion bar centers which results in a more level attitude with the higher front fender spacing.
