Hi thanks for all your help so far. I have basically bought a Freelander that I love with knackered IRD and probably VCU which I will change as well. Car is 1.8 petrol 1997 I was wondered what the best year of IRD to get? I know the later ones have better ratios. One other thing I think all my exhaust nuts are rusted on do you guys just cut through them with an angle grinder and fit new ones? All help greatly appreciated.
