Hi John, group,
I have actually been able to accurately measure the points on right side of that car to it's proper centre line as per Mercedes frame drawing to within 2mm. I am seriously impressed thta I was able to do this and actaully find this problem. It all looks pretty straights to the eye and even measing with tabpe measure does not reveal the secrets. it took several attempts and ideas to get to the point where I can now repeatedly measure all this and get the same results every time.
I am thinking to swap the whole arm by making a jig from 2 flat bars with holes bored into them to go from the right arm mounting point to the left.
That must then give the right distance left to right for the subframe to fit.
Then maybe 2 pieces of tubing straight down to the floor for the correct height.
Any ideas on that are most welcome, bearing in mind that I can't use the current arm as a guide because it is off.
I 'll be going to look see that donor car this afternoon.
Hopefully it is usable and does not have similar issues!
Here is a picture of the subframe. The straight edge (timber in this case :-) ) is supposed to lie flat across the 2 cups but there is quite a gap.
Regards
Bernt
