Hi, Discovery 1, I’ve got a standard heavy load terrafirma 2” kit fitted with bf all terrain tyres and as expected the rear drive shaft with donut is rebelling against me. Having looked into it the output flange conversion at the back with the double uv prop seems to be the solution. My question is, do I need a spacer with the 2” lift and has anyone done this exact conversion successfully without incurring any vibration that could tell me the exact parts used. There is a kit at around 105 quid that includes a spacer and I’m leaning towards fitting it unless someone advises differently?
