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.

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.

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