[torsen] Re: 89 centre differential

[Michael L. Riebs]

Suffolk Alignment managed to get my old V8 within 0.03° on the front, and
0.01° on the rear AND managed to make it so that the variance is the same
for each side of the car. It now tracks better than any car I have owned in
the past 7 years, and that means STR8!

How's that for within specs?
