clutch disc thickness (1 Viewer)

['69 Yota]

Hello,
Would anyone know what the thickness of a standard clutch disc should be for a 1977 2f/4 speed set up out of an FJ40? I picked up this set up for my FJ45 and while I have it out I pulled the tranny off the motor and everything looks pretty good. I got a gasket set with a new rear main seal, but this one hasn't been leaking and the clutch and flywheel look really pretty good. It doesn't look like there's much material on the disc though. There's no cracks or heat checks on either surface, so I'm wondering what the thickness should be before I replace it just to replace it. Thanks.

Unless it looks brand new, just replace it while it's apart.

I guess that was my point. It looks great. I just don't know how much matereal was there to start with. The throwout bearing looks and feels perfect.
