anyone know the above as i dont have one in front of me and just cant remember the size for some reason :)

If I remember correctly, they are 27mm long, thread is 1mm super fine pitch, 12.9 grade high tensile, think M10, very hard to get hold of and expensive from nissan, do you need some? I can knock you a set up, I had a box made for me, still got some, and have female allen heads (which I think are better), I have sold a few sets on here and used them my self....

i got some from my local nuts'bolt man ... just 30mm long

I've got a mahoosive nuts & bolts warehouse near me, Thomas smith fasteners, they couldn't get them in 12.9, took me ages on the net to find somewhere I could source them from, and I had to get 50....

thanks for the reply but i went arp in the end

I may be interested in a set - I am missing one bolt ( and a chewed out thread in the crank- grr!!) are they definately the hi tensile jobbies?

Have PM'd you mate.
