Tadek,
Your thoughts are the same as mine were, when I realized the misalignment
first. Then I started a thorough investigation and did lots of frame
measurements and even realized that the right hand front wheel was 1.5cm
further to the back than the left hand. It was only visible when you compared
the wheel arches and contours of the wheels in the arch. During this checks I
saw very minor signs of an accident, which was repaired I expect some 10 years
before I bought the car in 1986. At the end it turned out that the lower
wishbone mounts were replaced and welded back to the wrong places and with
slightly wrong angle. So it was some work to get the suspension right again.
Now to the precision of the factory work. I think the alignment was quite
good, compared to the body work. My right hand door on my BN1 is 1cm longer
than the left hand door! Both doors are the original doors.
I also have a accident free 1962 BT7, with most of its original panels on the
car. The alignment of the front suspension of this Healey is perfect. So I
assume the quality some 6 years ago was not that bad, as you realize it on
your car.
Put your car on a pit or lifter to check and measure all distances and check
for accident damage and you may find an answer to your questions.

Betreff: RE: [Healeys] AH 100 first driving impressions - Boy this is fun!...
Well,
Please correct me if I am wrong, but the camber really signifies the relation
of the upper and lower truunion while looking from the front of the car. This
really means there is a triangle between the upper and lower trueunion
|\0 <--upper truunion
| \
| \
| \
| \
|_____\O <-- lower truunion
The angle at the top of that triangle should be 1deg. The distance between the
top and lower truunion is about 22cm. This means that the lower edge of the
triangle should be almost 4mm. (if I remember my trigonometry correctly)
My triangle is the other way, moved 2mm to the outside.
This means my left side is 6mm off.
The question is - was this due to accident or was it the way the cars were
produced??..
How precisely were the cars manufactured as far as the frame is
concerned??...
What are the tolerances for these setups?
Thanks, Tadek
