Clutch disk differences - 70-74 vs. 75-83

[Arne]

As I prepare to swap a four speed in place of my car's automatic, I find that I almost blew it. The pressure plate that I was planning to use doesn't match the throw-out bearing collar I have. Not a big issue since I discovered it now, as I have the proper pressure plate as well.

But the new disk I have is the 75-83 225mm disk, not the earlier 70-74 225mm disk. Anyone know if there is really any functional difference? I have an early one to compare with, and there certainly doesn't appear to be any dimensional or design difference. Yet MSA's catalog does list a different disk for those years.

So short version - Can I use a 75-83 clutch disk with a 70-74 pressure plate?

Yes the disk will work fine.

Thanks, Jon!
