Hi Tom. Re. ZF versus Getrag, I should like to add a comment or two. I put a Getrag in to my 280SL, and it transformed the car, in my opinion. I also have an Alfa Romeo Montreal with the ZF , and the difference is noticeable. The Getrag has a much nicer shift, and the pattern is also more sensible. I couldn't confirm it as being far superior, as both do the job they were designed for, just that the Getrag is much nicer to use. Cheers, Dale.
