Unfortunately, although I've only done 1000 miles in it, I bought the parts 6 years ago and I can't be arsed with the fight. I'll just carry on telling all and sundry how crap their stuff is.
Were they not selling decent ones? Bought my CVs from JK years ago (they're GKNs I think) and they're still going strong. Always had the impression that JK are more interested in marketing than anything else.
I don't think there was an option but I don't really remember. I buy the GKNs from Brickwerks now, they're the same as T3 CVs.
