Manta B final drive

john17 · 07-17-2008

Hello. I'm from Romania and I have a 1979 Manta B which I use in hill climbing races. My actual ratio is 3.67 (stock) but I want to change for something shorter (>4). The question is: what should I look for? I know Ascona B 1.3 has a smaller diff with short ratio but it might be too weak... I don't know if the gears from Rekord C fit (Manta and Ascona B have an "wobble" connection with the propeller shaft). thanks.

Go to Risse Motorsport, click on <CIH>, then <Getriebe und Zubehör>, and you can buy all the rear ratios you ever want.

Not so many and pretty expensive... I found a 3.89 from Rekord but don't think it fits due to the Manta's wobble coupling.

The Manta/Ascona B 1900 N (75 HP) Automatic has 3,89 too.
Not > 4, but a cheap and available alternative
