rear wheel alignment
1972 c3 replaced all parts in the rear everything is new I'm trying to get the alignment to track the front I'm using string, laser, level, m-tap and anything else I can find. both rear are 2.5in. to the right from center to center of the rims. Anybody got any ideas or tricks they could pass on to get them to track straight the chevy dealership worked on it 2 hours no luck the kid looked 18 he is not old enough for these cars thanks for any ideas.

Its not difficult to get the wheels to toe-in balanced left vs right, just time consuming. (0 thrust angle).
Does the wheel toe-in when you move shims from inside to outside of the Trailing Arm ?
To align the rear.
1. set camber first
2. Set thrust angle.
3. Adjust toe.
Then recheck camber. If you need to re-do camber then check # 2, # 3 again.

you need to move the car after every adjustment to get it to settle to the new adjustments. I rolled it in and out of the garage and it seemed to do it. when using the string method I measured to the front frame in the wheel well. Use a flash light so you go to the same spot everytime. There is a rivet in there you dont want to get a false reading on top of. I also had my rims marked so I was able to take measurements from 3 different rotations incase the rim is bent slightly. I had the rear jacked up and the weight of the rear end (trailing arms and springs) on blocks so I could rotate the tires

Wow it seems so basic to set the rear toe on an alignment rack. Don't you just move the trailing arms shims around to set the toe and then adjust the camber via the strut rods? Or as suggested above set the camber first. Since everything is new it should be a piece of cake.
I've never tried the string method so I'm not help there.

When I did mine, I measured off the straight parts of the frame on both sides under the doors to set my strings. Then when setting the toe I knew it was inline with the frame. Did the fronts the same way.

Thanks for all input, I got it figured out The problem was BABA not the car. When BABA put on new trailing arm bushings he didnt press fit them just stuck them together. I had started going over every part until i found the problem. (BABA) String line works fine now. The dealership was thinking i had a bent frame. Car is on the road after 1.5yrs work and I still have some hair left. (didnt pull it all out) THX, mb
