Rear axle: LSD or not?

I have been investigating unsuccessfully to know if the vintage V8 Masers using a rigid Salisbury rear axle, (QP1, Ghibli1, Indy, Mexico) were equipped with a LSD.
It seems that the Ghibli's were fitted with one while the Indy's were not (or maybe as an option only).
Anybody can bring some light on this?
Also would a LSD retrofitting on a 4900 Indy be eventually possible and do you think that would be worth?

 

My late Ghibli SS does NOT have a limited-slip.

 

So it would seem that it was an option on the Ghibli also...
I have looked in the Spare Parts manual of the Indy and in the picture here under the optional LSD is figured out as the group number 31:

Froggie: I am not sure the LSD was actually an "option", especially near the end of the Ghibli run. The Company was in such dire financial straits, that I suspect they were saving funds any way they could. Why pay for LSD units if you do not have to, and most customers would never know the difference.

 

Stay away from LSD.......

 

At least it was an option on a Maserati 3500 GT.

In my built sheet is listed "Autobloccante", which is the italian description for limited slip differential.

And I am sure, that every Salisbury axle can be converted, but it costs a lot of money.

 

Interesting.
Have you ever experienced its presence, say on slippy turns?

 

Not yet tested, still under restoration.

But some friends of mine with similar cars are quite happy with it, if you drive sportier.

 

To update this thread and for the record:
I had to replace my diff because of broken and loose attachment bolts between crown and carrier.
I was fortunate enough to source a Jaguar/Salisbury LSD that had been reconditioned, for only 350 EUR, it was a good deal.
See the story there:

It was fitted like a charm, actually I believe it is exactly the same diff that was offered as an option for the Maser GT's of that period.
See here the original open diff and the Jaguar LSD with the crown already bolted on but without bearings yet:

Now just to be driven when the restoration is completed

 

The Bora has an LSD... the clutch style I believe.. and I've felt it on strong turns...
If the Bora even counts in this discussion...?

 

Jack up spin tire and that will tell you

 

Yes indeed, and it is of the clutch style.
Though it seems to be a different model with a different assembly of clutches/plates compared to the Jaguar/Salisbury model mounted as an option on Indy's or Ghibli's and as standard on the Khamsin.
Here are the exploded views in the parts manuals.

For the Khamsin:

How is it tuned in the Bora, or said differently how does it behave in terms of understeer/oversteer on turns during braking and during acceleration?

 

I can't separate how the Bora LSD affects the handling dynamics as an individual part of the whole suspension design.. but the LSD makes itself known when launching the Bora from a stand-still while making a turn. As you can imagine, that causes one of the rear tires to "Chirp!".. and it wants to understeer. I've never sensed the LSD during any kind of braking.
