Stoney I will happily give you a hand sorting kits out mate, and my car will be at Wickstead Park, 9 - 11th September, if you would like to use it to work out what bolts are required?

The failed bolts in question, I think, were fitted by my car's previous, previous owner somewhere between 3-6 years ago, and removed by the previous owner and refitted, without issue, (very approx) two years ago. My guess is that they were not designed for that purpose. I'm sure yours are fine!

DaveEdin Darn you beat me to the "offer my car as the sample" trick :lol:
