thanks for the replies chaps.
Ajax, I thought you'd know the score, they have agreed to send me out the correct discs now, well correct in a loose description, but they are 67.0mm bore, which is a better option than going with mickey mouse spigot rings but still means that the kit is not just a straight fit as i'll need to get them turned down now .
Jase , the kit did come with all the bits and the bolts are not an issue now as the discs were wrong, all the rest was included.
Jimbo, you are correct chap in your reply, which is exacty my point really , the kit is advertised as all you need to do the conversion , with the correct parts, no suggestion that the discs will not fit directly without being machined down , so effectively the kit is not proper conversion kit , its just a collection of parts some that fit and some that don't, still not happy frankly.
