1.5L Rear end?

[soybean]

While cleaning up the rear end in preperation for repainting with POR 15, I came across 1.5L stamped on both undersides of the bottoms where the springs set. Somewhere in the dark recess' of my feeble brain, I seem to remember reading that the rear ends of the Gts,used the rear ends from the 1.5L Kadette series. Is this correct? and would the rear end from a Manta series work? or would the bracketry from the Manta be different because of the sway bar? Is there a way to make it work, or should I just go ahead and get a rear sway bar from either Addco or Opel Gt Source? Thanks again, Jarrell

Can't speak if its a 1.5L or not..

But a Manta rear will not work in a GT with a lot of mods.

The Kadett 1.5L will though and its a 3.18 rear end. Which is whay they have been installed (For highway driving and MPG)

The 1.5L 4-speed 1968 Kadett originally came equipped with a 3.67 ratio "rallye" rear axle.

Compared to the standard 3.44 rear axle, it will lower your highway top speed and will cause lower gas mileage, but it will enhance your performance in low gears from a standing start.

The 3.18 axle was originally installed only in 1.9L Kadett Wagons (1968-1972) with an automatic transmission. It will cost you low-speed performance, but adds high-speed efficiency, and as such is best when installed with a high-torque Opel motor (such as a fuel-injected 2.2 or 2.4L)
and a 5-speed GETRAG transmission.

The only way to know if you have a rallye 3.67 axle, is to remove the plate from the differential and count the teeth on the main gear.

31 teeth = standard 3.44 ratio.
33 teeth = rallye 3.67 ratio.

One advantage of the 3.67 axle housing, is it has been described as larger than standard 3.44 Opel axle housings, and has been used for installation of taller Quaife-brand 3.89 and 4.11 gears (ask "Rally Bob" for more information on those).

Please be cautious, regarding the source and accuracy of the Opel information you rely on -- If misrepresentations occur (such as during a sale of an Opel part as a 'performance' part, when it is no such thing), then you can be vulnerable to a charge of misrepresentation or fraud.

Good to see you posting either way. Your insight and knowledge would be really apreciated here if you have the time.

Allow me make one small correction to this generality:

1968: 3.18 was used in ALL 1.9 Kadett models, MAN and AUTO, except in the 1.9 Rallye. 3.67 was used in all 1.5 models and the 1.9 Rallye. 3.89 was used in all 1.1 models. There was no 3.44 rear end offered.

1969: 3.18 was used in ALL 1.9 AT Kadett models except the 1.9 AT Rallye which had a 3.44, which was also the ONLY rear end ever offered for all 1.9 GTs, MAN and AUTO. 3.67 was only offered in the 1.9 Rallye Kadett with MAN. 3.89 was offered in all 1.1 Kadett models except for the 1.1SR powered wagon (39) and Rallye (92) which had a 4.11.

1970: 3.18 was used in ALL 1.9 Kadett models, both MAN and AUTO, except for the 1.9 Rallye which used 3.67 MAN and 3.44 AUTO. ALL 1.1 powered models used a 4.11.

1971: ALL 1.9 models, both MAN and AUTO, used 3.44 except for the Manta Rallye MAN which used 3.67. All 1.1 Kadett models used 4.11.

Thanks for the clarification, as I am freely willing to admit, I do sometimes make mistakes. But I knew it was something like that.

Ok I'll voice my opinion yet again. Yippee wow thanks for a bit of the past and the promise of a good Opel future. If that is a hint you are taking over the OMC let me know where to join. You have pulled me out of the mess I get myself into and my support is completely there for ya. Please keep up the great work.
