Diesel Audi trans ratio's ?

Would anybody be able to tell me what the ratio's are for a diesel Audi transmission <manual> from a '82 4000s. I would assume it would give the car a higher speed sue to lower gearing of the lower revving diesel motor. I have been unable to determine these ratio's by "googling." Anyone have any leads on this.

Thanks for any information.

Also if anyone happens to have or know of any "UMETS" from Fiber Fab hanging around, drop me a line $$.

Thank you again.
