That's why the bushing should be inspected before buying new ones. I'm sure BeeJJ is not going to buy them first, only to find out they are perfectly fine and didn't solve the problem. The Caster article gives a spec for the bushing thickness.
If the wheel alignment guys are correct that the right strut is bent, simply replace the strut. It is non-adjustable in stock form.
But shoota's still correct, camber has little to do with the tyre hitting the back of the wheelwell. A bent strut is unlikely to cause that, as it is fixed at the bottom by the caster rod. A bent spindle might cause it.
What's funny is that TWO wheel alignment shops couldn't fix it. Back in 1981, that was the first repair to my 1200 -- the right wheel hit the back of the wheelwell, and the local alignment shop fixed it.
I can't read the handwriting to see which parts were changed.
