RS5F41 Gearbox Final Drive Options

[Micra_Marcos]

Hi Guys,

First post on here, and I hope that this post is in the most appropriate place?

I am building a 1980 Mini Marcos with a Nissan CG13 engine. Because of space constraints I have been forced to bolt on a RS5F41 gearbox.

I believe the final drive ratios are 4.0:1 when fitted to the K11, and 3.65:1 from the K10.

Are there any other final drive options available for this particular gearbox, I need to go as low as possible.

Regards

Craig

Thank you Frank - Would you know if the final drive from the 4 speed @ 3.591 can be fitted to the RS5F41 ?
