Fitting a clutch servo kit

I find the clutch pedal very heavy to push on my TD5 defender due to a knee problem.

I have found a few people have fitted a clutch servo kit to reduce the clutch weight by up to 70%.

Has anyone on here fitted one and can they recommend which kit or parts I will need?

Hi We are a small development company, we have recognised the need to find a solution to the TD5's hard clutch. So please see the video in youtube
