Re: LSD confusion

["John Hertzman" <johnhertzman@domain.elided>]

Jacob Haagerup writes "John H. corrects himself as to the presence of LSD on
all post 1972 Giulias and I can confirm that not only the Supers had no LSD.
The Juniors didn't either."

 It is of no great importance, but if Jacob misunderstood me undoubtedly
others did too. My correction of my error was on a quite different point. The
105/115 cars received in the United States had two different basic rear axle
designs, easily identifiable by the details of the center section, its sump
plate, and the bearings, seals, and ring-and-pinion sets which they accepted.
One of these rear axle designs was used, on the US cars, from the introduction
of the 105 through the end of 1750 production, and the other was introduced,
on US cars, with the 2000. Both axle designs were produced with conventional
differentials and both axle designs accepted one or the other of two different
limited-slip units.

 The error which I was correcting was that I had assumed that the change was
related to date of production- that all cars through 1971 had used one, and
all cars from 1972 had use the other. That assumption was wrong; evidently all
cars from 1300 cc through 1750 cc used one design, regardless of production
date, and the 2000 cc cars used the other.

 Since (according to the parts books I have) there were no differences among
the 1300, 1600, and 1750 axles which could affect the fitting of a limited
slip, the limited slip units offered as an option on the 1750s and some other
earlier cars should fit any 1300, 1600, or 1750 105/115 cars. But I never
meant to suggest that all cars of any particular size had limited slips; only
that there were limited slip marketed by Alfa which would fit any axles used
in the 105/115 cars, and that all of those axles were also produced without
limited alps, and that consequently the external forms of the two axle designs
were not totally reliable indications of the presence or absence of a limited
slip in a particular axle.

 Sorry if I was confusing -

 Cordially,
