extreme wheel alignment problem -- need help

Hi folks.

I've been driving my new to me 70 Duster for about 1500 miles this summer between the raindrops. I got the slant 6 running reasonably well. When I first got the car the alignment was terrible, it went all over the place and the steering wheel didn't return to center.

Got it aligned and it drove very nicely, just a very slight pull to the left. Nothing I couldn't handle. Then last weekend I parked with my front tires turned all the way to the left and noticed that both tires were shaven down very bald,especially on the outside half of the treads. So this is bad after only 1500 miles to go from tires with about 1/2 their tread left to nothing.

I don't think I'm extremely toed-out(but I'll have this checked out), I just seem to have alot of positive camber. The tops of my front tires are visually way more out than the bottom of the tire. Now that I look at it from about 20 feet away in front of the car.

I'm hoping I don't have extreme front end problems and it's weird that the alignment shop didn't notice this.

But anyway I was reading the thread in this forum by Zinger74, alignment issues, #67779. I didn't realize that tire wear can be greatly affected by ride height through the torsion bars. I'm unclear though if i need to raise or lower the front end to get rid of my positive camber??

Thanks for any help.
