    Not sure if they would be long enough though Norbie. They are probably the same length as the 5speed ones.

    I can measure then up when I get them on saturday/monday if you like. I have a set of bolts from a 1JZ/Flexplate to compare them too aswell if thats of any interest to anyone.

    Same diameter clutches though, 240mm. 7M is a 240mm clutch as well. Same spline diameter too. But from what has been posted in the other thread they dont bolt up.

    Also, the ARP bolts are of the length of the R154 bolts.

    GTE and GE the same diameter in 7M? I'm sure someone told me I couldnt use a GTE flywheel with a W58 for some reason. Therefore I assumed the GE flywheels were the same diameter as 5M jobs. Learn something new every day

    Edit - Interestingly I also just pulled a 225mm clutch out of my lexus and replaced it with a 240mm. I wonder what the 225mm job was meant for? It was (obviously) a JZ stud pattern...

    In case it's not common knowledge, 1JZ-GTE/R154 and 7M-GTE/R154 pressure plates and clutch discs are interchangeable despite the different flywheels.
