65 b'cuda windshield install--help!

I'm going to install my windshield now that I've cleaned, prepped and painted around it.

I'm thinking I need 1-2 ppl to help me, thoughts?

I'm also thinking I will add a windshield sealant around the a pillars to prevent future rust again, thoughts?

And should I install the gasket to the window then in place, or install it to the pinch weld and add the window?

Thanks
