I'm a newbie here, with a flywheel question (1 Viewer)

[YukonD]

I'm a new member here, and working away on my '72 FJ40 (3.9L/3 speed tranny). Currently I'm replacing the clutch and about to get the flywheel resurfaced.

Can anyone tell me what the original thickness of the flywheel would be? Thanks!

I think that info is in the Haynes book as well. Haynes is better than nothing but the real books are way better.

Thank you!
I talked to the tech today at the machine shop and he told the wheel was stamped with that info. I didn’t realize that’s what the numbers were for!

It’s great to get the responses to my question. Thanks everyone.
