Thank you fro the replies
Yes, you are right, for the price, why bothering ? But it is always a mess to find these kinds of "special" items here for me, so if I could have avoid such researches, I would.
And I guess if I go directly to Ford, it will be £14... for 1 bolt
But I will definitely find them and put new ones, saving on this is not worth the risk.
Thanks again.
