Hey Johnboy, what'd you end up going with?
I'm in the same boat at the moment, looking for a new Stage 2 /HD clutch, and probably going to go with an exedy.
Have just bought a 240z with an L28, pulled the gearbox and clutch out, but can't figure out what I've got exactly. The clutch assembly measures 47mm, but is there anyway I can determine what model the gearbox came from, and what model the clutch collar came from too? (previously owner isn't sure)
Thanks in advance for anyone that can help me
