Depending on the donor car, you will need all the associated parts to include all linkages (clutch pedal and shifter), entire pedal assembly, z-bar, bell housing and all brackets.

I lived in England for three years. I was US Air Force stationed at Greenham Common (Newberry). My Mom (me Mum) is from Devizes, Wiltshire. I've got a lot of relatives in Devizes.

Good luck on your search for a donor car. Once you locate some possible cars for parts post them up here, (with pictures) and we can point out what will work for your swap.
