My local
'All Parts' store offers a set for £57. At that price I doubt they'll be genuine Toyota parts. Not sure yet but I might take the risk, it's got to be better than my current leads.Cry, did you decide what leads to get in the end? Doesn't look like GTSChris is trading any more.
As I understand it rev2 onwards are all 5mm leads which I assume refers to conductor diameter.
