Wheels alignment. After frame lift

Hello,

I have done a "frame lift" on my 1976 Corvette. All has been taken apart sandblasted and repaited, bearings, bushings, ball joints, shock absorber have been replaced.
Now I need to get the wheels to "point in the correct direction" again.
I live in Denmark and I do not think the workshops has the "values" it has to be adjusted to.
Do anyone have some "values/measurements" which the car has to adjusted to?

Kind regards

Check out VB web site for some alignment numbers.

I just had my wheels aligned after replacing the cotrol arm bushings. The shop gave me a printout that shows my number all in the green and supposedly OK. All numbers however on my sheet measured in degrees while one meausurement on the vbp sheet was in inches. Is there a way to convert and even the degree measurements dont seem to coincide. Can anyone make heads or tales of what I have? I can post a scan later tonight or describe the numbers now.

That 1/32 translates to 1/2 deg? My front wheel settings are as follows:
For camber it says 0.04 deg on the left side of the printout (left wheel?) then it says -0.02 deg in the middle and 0.6 deg on the right side (right wheel?)

For caster adjustment left side of printout 1.6 deg, middle -0.4 deg and right side 2.0 deg.

For Toe left side 0.34 deg and right side 0.14 deg. for all measurements there is a green bar with what appears to be an acceptable range. All my numbers fall inside this range. At least thats what the shop said.
I should just scan it and post it.

It's pretty normal to measure toe in inches. I think I have the degree measurements in one of my old Hunter books, I'll look later.

caster also needs to be equal from side to side. 1.6 and 2.0 is not to bad but the car may pull to one side while driving.

Camber = -0.5 for street driving should be max
+0.02 and +0.6 is terrible

Toe = 1/32" to 1/16" toe in total for street driving.

This is why I set up my own alignment. Most shops machines have a very wide tolerance +- 1.0 degrees. Getting the computer to show green for all the readings is not tough.

Take the car back and tell them that is pulls terrible. Have them set the alignment as per the VB sheet or above and tell them to make things equal. If there is -0.75 degree camber on the left is should be -0.75 degree on the right. Ask them also once they are done to drive the car around the block to reset the suspension and then verify that the alignment has not changed.
