Did mine today and has made a noticeable difference which was great. Great write up and easy to follow if not a little tight working upside down in the footwell. Couple of tips that worked for me. I used a small nail that are generally found on electrical clips for house electrics. Fitted well in the hole and didn’t slip through as they have a flat head. Also used a decorators extension pole instead of the clothes line as easy to adjust the length which helped me in lining up the pedal.
Purchased from local OPC as there are many options on the parts list. Cost just over £50.00. I always felt the clutch was a little heavy but not in the sense that it was on its way. Pedal now feels softer. Couple of images of old spring. On a side note the lugs on the new spring we’re slightly different and a little smaller, if anything made it easier to fit back in. If you haven’t done this and decide to give it a go don’t be put of when you remove the air pipes and look up into the space. My first reaction was this is never going to work with out removing half the dash. Follow this guide and all should be easy. First photo shows the pin I used
