Guys-I'm trying to put together a buy of an assortment of parts for several cars; one being a 66 Giulia 1600 TI project car that came with no engine, trans or driveshaft. I've got good cores now on the engine and trans and may have found a driveshaft but need to verify the length of the longer 2nd portion of the DS

I do have some access to a 64 to check specs but in my research, there seems to be an indication that there were differences in Giulia length early vs late. (I'm guessing that 64 and 66 are both considered early but I hate guessing). A seller of parts has several rear portion DSs to choose from but guessing is an easy way to waste money.

I've consulted the factory service manual, the parts manual and did a BB Forum search under the prompt "Drive Shaft Length" and looked at all 469 titles and the brief intro in the search as well as every posting originating in the Sedan forums-nada, zip, nothing- No mention of the length. As long as I'm asking , what is the dia of the shaft?

I'll be running a 2L street car and while I understand the 2.0s had a larger dia , Giulia/Berlina DSs in 2.0 configs might be harder to locate=any concerns with running the earlier thinner diameterDS?



According to the Giulia parts book, the part number in question had two numbers-an original and presumably a revised version. My version has a "correction" in red ink indicating a new number.

Original 105.48.15.017.03
Revised 105.12.15.017.02

Please advise and thanks-
Steve

For the front section: Spider, GT and Giulia are identical in length. 1750/2000 Berlina is longer.

For the rear section: Giulia and 1750/2000 Berlina are same length. GT is shorter and Spider is shorter yet.

Differences between early and late Giulia are the types of U-joints and the center support bearing, as well as diameter.

The rear section of the 2000 Berlina uses 9mm rather than 8mm bolts and requires drilling of the pinion flange unless a 2000 rear diff is used.

Yes, agreed, known and understood. My question, put more succinctly is "How long is the rear section for an early TI or Super" or for that matter the Berlina and 1750/2000?

My prospective vendor has a pile of Alfa driveshafts and I need to be able to tell him how long and I'd like to be more specific than "the longest one in the pile"

Again, I have a 66 TI and I''ll be dropping in a 2.0 with 5 speed.I'm assuming there are no differences in casing length between the original 1600 set up and the 2000 config
Thanks for responding

FWIW, I seem to recall finding out that Berlina and Super shafts are different lengths, due to longer wheelbase on Berlina, I may be wrong, and it wouldn't be the first time. Classic Alfa has aftermarket rear shafts for Super and no where does it mention Berlina's. I suspect if they were the same length CA would love to sell them for Berlina as well.

Late and early Giulia shafts are identical in length. I run a late shaft in my 64 TI with a modified carrier bearing - 2 liter and 2 liter LSD.

And I run a stock late shaft in my Nuova with a 2 liter LSD.

I am also familiar with racers who run the early shaft w/ 2 liter for weight reasons.

Thanks to all who responded and for their suggestions and assistance. I've located one with a NOS tag on it with 105.12.15.017.02 which matches my parts books.

compressed length is 930mm or 36 and 5/8. The newer stuff (not the originally installed-as I understand it) has 9mm mounting holes. As most of us know, specialized bolts-see Classic Alfa and others for details.

Hi Austin Alfa,

What I found about the Berlina rear shafts in the catalogs:
all 4d Giulia cars (1300 & 1600) started with the rear shaft 105.00.15.017.08 that had diameter 60 mm .
That shaft was exchanged for the 70 mm 1750 Berlina 105.48.15.017.03 shaft in 1967:
  • on the Giulia 1300 TI
  • probably not on the Giulia 1300
  • on the Giulia Super from chassis # 862001 on.
  • probably not on the 1600 TI
This all is from what I saw in the catalogs !

The second change, from 105.48.15.017.03 to 105.12.15.017.02, involved the change of the bolts & holes going from 8 mm to 9 mm.
I can't see exactly when this happened but probably in 1971, at the arrival of the 2000 Berlina ( which is type 105.12 !)
  • The 1/1971 Giulia-1300-Super catalog still listed the 105.48.15.017.03
  • The Giulia Super 1,3 & 1,6 catalog from 3/1973 lists the 105.12.15.017.02, as does the 1974 Nuova catalog.
  • The 6/1974 Rapido catalog mentions the 105.12.15.017.02 shaft ( with the 9 mm holes indeed ) for all Giulias & Berlinas, from the 1300 to the 2000.

Rgds,

Thierry

Thierry,

Thanks for the additional information. It seems that only having 2 parts books is not enough! It's a challenge putting together an incomplete car.
