I've got a Givi rack for a B12 with most of the fastenings missing. I can easily bodge most of it but there are a two things I can't bodge so easily. Namely spacers/bushes to slot over bolts. A spacer to slot over an M6 bolt: 14mm long 10mm external diameter. A spacer to slot over an M8 bolt: 22mm long 12mm external diameter. Steel would be best. It does need to be strong. I've tried places that sell standoffs, & all my local fastening places. At a push I could just use a pile of washers (I think most pipe would be too thin) but I'd rather do it nicely and buy them off the shelf. Anyone know somewhere that will do this kind of thing without a 100 euro minimum order?
