Stiff front end looking at aftermarket solutions

Ok thanks for your response.
lets see if i can answer a few of these.

I have already disabled the hole thing and all the suspension Weighs 65 LBS per side.

Car goes straight and center by itself, after a turn so no tight ball joints. All Ball Joints, tie rods idle arms, pitman arm, are all Moog part. Some 20 +year old Moogs but still in good conditions.

When i separated the upper control arm from the spindle the spindle fell down and the upper control arm didn't move. took grate force to move it up and down, and that's were the squawk is.
The bushing are factory bushing that i hollowed out the rubber and pressed in urethane bushings(also 20+years ago)

The one cam bolt came right out, the other required a light tap with a hammer. then a wig L jug L to remove it. same thing to get the upper control arm out after the cam bolts were removed.

As far as the upper and lower bump stops.Both have made clean spots so i'm getting full suspension travel.

These are the parts i'm replacing....should be Way Way smooth/free "R" when i'm done.

Adjustable Upper Control Arms for 70-74 E-body
Adjustable Strut Rod, 70-74 E-body

Looking for a good deal on some /6 aka drag racing torsion bars.
found one place but it's a .845 and not so sure that my original 318 ones are around that size
