I asked the question as i have a mini xpress that i bought second hand. It came to me with a 64dp spur so want to replace that with the "equivalant" in 48dp. Suppose i shoould have posted in general car talk, but i now have my answer.
Stevo (Darren) not making excuses, but i have been away from racing for a 12 month period so im not so bothered about ya beating me. The thing is, when i get back into the swing of things, normal order shall indeed be restored and you will need them lucky underpants to wipe the tyre dust of ya face pal.
