I don't know how complete the cab was at the factory for that assembly instruction. Given the nature of the rubber bushing shackle, it would settle a touch after adding load. But the critical thing is to get the rear cab shackle set correctly along with the front cab mounts, and the radiator support. After that, if a couple of people pile in (on average heavier today than they would be in the '50s) whatever movement is just what it is.

I would use that 0.76" with a fully assembled cab and let it go at that.

Moving to Paint and Body because it's more on topic there than in GTT.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
