Oh dear. Just as an afterthought I've asked the place who are fitting my tyres and wheels tomorrow whether I should bring my own wobbly bolts or if they would supply them. To discover the chief man there has never heard of them (even following my not very technical description of them over the phone). Is this a good time to panic? I'm now off to Halfords to purchase some, but is there anything I should know that I should tell these people tomorrow about my flashy bolts or HOPE they have a vague idea of what they are when they see them?
