For street and strip. I cant find my specs that i use for my cuda and its been over 10 years since its been aligned.
i thought it was something like 2 or 3 negative camber and 1/8" toe in.
anyone have some good numbers for a mixture of curves and straights?
im getting it aligned tomorrow
As much caster as you can get up to about 5 degrees positive
.5 to .75 negative camber with radial.
1/16 toe in.

The way you list the toe would lead me to believe you have .25 which is way too much. Toe is usually expressed as a single number, and yes its the relationship of one wheel to the other.
You now have postive camber.....hummmmm. I would have sacrificed whatever amount of caster was required to get you to 0 camber.
Rather that new UCA's the Moog offset bushings will remedy the problem nicely.
Jumping up and down.....not sure---maybe the excessive toe????
 He took what you wanted to literally. Or he didn't understand the concepts enough to know the order of importance and minimum levels of the specs/requests you asked him.
I think you might need to find a better alignment shop. That or something is really lacking in communication.
-Adjust the caster to the greatest amount with rear cam adjuster all the way inward and front all the way outward.
-Then bring in front adjuster to get to at least 0 or .25 negative camber.
-Then do the same for the other side.
-Then go to the side with the most caster and adjust the front cam adj. inward so the caster is about halfway toward the other side's number.
-Then adjust the rear cam adj. out enough to get the camber match other other side.
That should get you pretty close. Then you have to go back and forth with the front a rear adjuster to get the camber and caster to match the other side.
The camber should be a minimum of 0 or .25 NEGATIVE (top of tire in).
The reason it pulled before is that the car had cross caster. One side was negative (-1.7) and the other side was positive (1.2).

I set my ride height ahead of time after once it came back too low, 0 camber, as much positive caster as they could get(but the same amt on each side) forgot the toe in but iirc 1/16" to 1/8", all with my weight in barbells in the drivers seat after I get there, the tire psi where I want it, a half tank of gas, also told him to tighten the uca cam bolts TIGHT when he's done(the 65 lbs spec is too low) & a $20 tip for him to get it where I want it. My 65 dart tracks perfect 
If I cannot do it, I ask the alignment guy what the first step to a Mopar torsion bar suspension alignment is. If he doesn't say set ride height, I move on.
There used to be the disclaimer: torsion bar suspensions extra on alignment prices because of the extra step.

Alignments can be done properly at different ride heights. Mopar was the only one that allowed a height adjustment. Granted mopar has specs with ride height setting to make bump steer a minimum.
As far as ride height goes all cars should be adjusted at the factory recommended height. I always made sure the right to left was even and the car was not nosed up or down at a bad angle.

I assume you are using teh degree plate to measure the degree of turn on the wheels as you measure caster. Wha degree are you turning to? 20 degree? 30 degree? I would be interested in knowing this. Thanks.
"IF YOU'RE UNDER CONTROL, YOU AIN'T GOING FAST ENOUGH."
If you are doing it on some sort of modern alignment rack the machine will tell you the angle or set point.
A Longacre caster camber gauge can use a degree plate, but there is also an angle machined on the edge of the gauge. You turn the wheel until the angle is paralell to the car. OR mark the rotations on the steering wheel (tape mark on wheel) and make sure the wheel is turned the same exact amount both ways from center.

I highly recomend a longacre type guage.
How do you use this gauge, I can not see a good way to attach it to the wheel? Most wheels do not have a machined flat serface to attach the gauge to...
What do you guys do...
I bought the Fasxtracks one with the 3 arms that contact the rim edge...

not very close. im in Arkansas.
my alignment guy isnt a a total idiot. he tried to get me what I asked for. but said that if he adjusts the canmber to negative, my caster goes all to hell. then we talked about what he could get me for camber if he set the caster to 2.5/3.5 and let me know that I'd be at positive camber.
me, not knowing anything said go ahead and go for as much - camber yu could at 2.5/3.5 and thats what he did.
if i'd have known the -camber was that important, i could have had him set it there. i'll also ask [Edited by Moparts - Keep it clean] is up with the toe numbers and get them straightened out
I'll take the car back there and have him try that. he's giving me a buddy deal so its not costing all that much.
the good news is that the car seems to drive fine. i guess that jumping i felt in the wheel must have been the road cause i havent felt it again. I drove a good 100 miles or so this weekend and ran it down the track and it felt fine in the corners (although i did squeek a little doing some cornering at faster than normal speed- i guess thats the + camber coming back to haunt me) and it felt fine at the drag strip.
