which model berlinas had the 4.10 rear axle, if any?

Assuming for the 1750/2000 105/115 series cars, none. That I can find anyway. All US 1750 & 2000 Berlinas have a 4.56. The Euro 1750s could be had with either a 4.56 or a 4.30 and the Euro 2l with manual trans also had a 4.30. The only possibility is the Euro 2l with auto trans but I haven't been able to confirm the ratio.
Any of the 750, 101 or 102 series Berlinas may have had a 4.10 but I didn't research those. Should I?

the car in question is a 2000 berlina, the book lists 4.30, which I thought to be a typo, but regardless it's a USA model, so 4.56 must be it.

I'm not to sure about this book anyway, lists a 1976 GTV (not Alfetta) as 4.10 along with the Berlina with 4.30 the ratio's are probably right but I thought both body styles were out of production at the end of 75

The book your using sounds accurate to me for the Euro model cars since I also have listings that the Euro GTVs & Spiders came with 4.10s. I can't say about the Berlina but I've read on this BB that the Bertone GTV was produced as late as 1977.
The 2l US Berlina, according to the owners manual anyway, came with a 4.56.

Guys,

The late USA Spiders had 4.1:1 differentials. I installed one in my '76 autocross Spider to make a "longer" 2nd gear. I think this was worth an additional 7 MPH in 2nd gear at 7500 RPM.

I bought a complete axle from the old Prestige imports in Cincinnati. Such a piece should bolt right in to a 105 series Berlina, right?

George, of course, is correct. The later Spiders (don't know from what year though) came with a 4.10. I should have added that the cars I was referring to were the 1750/2000 cars, both Euro and US, from 69-74. Sorry.

Euro 1750 Berlinas came with a 4.30 rear. US Spec did not. The US Spec 2L Berlinas have a 4.56 LSD rear. That's all I know.

I think the Spiders changed to the 4.10 in '81.

This is what I know:

9/41: 1300/1600 Giulia Super/ GTV / Spider
9/43: 2000 Berlina
10/41: 2000 GTV/ Spider
10/43: 1750 Berlina / GTV
16/46: Berlina automatic

Have tried the 16/46, but in 5th at 150 km/h and 3000 Rpm

, there was no reserve for accelerating anymore. Though 115km/h in 2nd was fun

!

So I am going back to 10/41. Is best solution with 150 bhp.

well, I've an 8/43 sitting in the shop. tried it on my GTam rep, which was huge fun, but a top speed 50 klicks lower.....170 @7500 rpm... Highway driving , 120 km/h at close to 5000 rpm is no fun! Not to mention gasoline...
I believe this is from a single carb 1300 Giulia.
also, I believe , Tazio, that it isn't 16/46 but 15/46. Didn't you make a mistake in counting? And didn't US spiders have a short ratio LSD?
