Good job doob! Those pretty much match what I have in my books dead nuts.

Note: Those specs are for factory components. Some aftermarket parts will require different torque specs.

 

[Doober]

Hopefully it should match, it's from a Chevrolet factory manual! :mrgreen:

 

[80ECLT]

HAHA! True!

I would add that all the A-arm & rear suspension hardware should be torqued with the car on the ground, or at least with the tires at ride height, unless you have Delalum bushings or spherical bearings.

Do you happen to have the specs for the outside uca shafts torque specs?

It's likely if they're included in the manual, but those are up in Michigan :?
