Micra Challenge Final Drive Kit

[Billy Quiz]

Hi there, I run a Micra rally car but it only has a standard 1.3 box in at the moment with a final drive ratio of 3.8:1 (I think), I know some kits were manufactured for the Challenge in the nineties which took it to something like 5.1:1 which is perfect for rallying. Has anybody any idea where I could get one of these kits, or a box fitted with one?
Also, the reg on the car is K11 NME, which is obviously pretty cool for a K11 rally car and I've someone who's expressed an interest in it. It's a nice reg, but at the end of the day it ain't making the car go any quicker! What do you reckon it's worth?
Many thanks in advance

Yeah I've spoke to Matthew and get most of my bits from him, but he doesn't have any challenge boxes in (it's different to a dog box in that you just change the final drive, hence it's cheaper to buy & maintain).
