Dan6061 Posted December 13, 2010 Report Share Posted December 13, 2010 M15 bolts are pretty big, get a picture of them up and we can tell you. Quote Link to comment Share on other sites More sharing options...
Shaun H Posted December 14, 2010 Report Share Posted December 14, 2010 Measure the bolts across their threaded part. If it's 15mm then they are M15 bolts, if it's 12mm they are M12 bolts and the Echo bolts won't fit. If this is the case then you can get M12 bolts from NC-17 in various colours here!
