74 Dart Lifting front end/ replacings springs

Can someone help me to get more space in the front end. I have some specific tires I'm trying to fit but I barely rub. I need just an inch or so more on the height of the body.

Does anyone know what size springs are on a 74 dart swinger?

It's a torsion bar suspension. You can raise the front some by cranking the preload up. The large bolt under the lower control arm. Make sure to raise the car up so there is no load Turn them equally a little bit at a time. Then have the front re aligned

I have read before the suggestion to realign the front end after adjusting the ride height. Maybe I have just been lucky, but I have never felt the need. I never felt a difference in the alignment after raising or lowering the front by an inch. My cars didn't toe in or out more to any point I could tell. The camber change would have been tiny if anything.
I'm not advising against it. I'm just saying that with only an inch of height change, the alignment should still be pretty close to what it was.

Your tires will tilt inwards after you crank up the torsion bars.

Within limits, you both may be right. Cranking the T bars up/ down DOES affect alignment, but these cars originally called for alignment settings which cambered the tires out at the top for bias tires. Modern radials call for the OPPOSITE, IE the tops of the tires cambered IN.

Here is a widely accepted standard for aligning these cars for use with modern radials instead of bias tires:

Scroll down to the "skosh chart" which calls for NEGATIVE camber IE tops of the tires cambered inwards.

What does this mean?
More Camber?
Less Camber?
I never noticed in my cars. Must have been the clean living!

This is all great stuff! I did have a rough patch over the weekend. Got the front end up 3/4 of an inch and the turn radius now clears. But this also accentuated a very bent A-arm/bar. thing. (you guys know of what i speak)
So I had it hoisted at a shop and a gentleman said he could reweld it, but it won't be cheap at $70/h for labor+parts. I've consider installing new parts?
opinions?

Camber goes two ways. tires "in" at the top, tires "out" at the top. Originally, older bias ply tire alignment settings were "out" at the top --look at most any old car or truck with a "straight" front axle. Usually you can see that

Modern radials like the tires "in at the top" as sugessted by the All Par Site

If you actually read this page, and look at the "skosh" chart, it will become clear:

http://www.allpar.com/history/mopar/...alignment.html

So absolute "plumb" is zero camber

"More in at the top" is "more negative camber"

"More out at the top" is "more positive camber"
