Rear window removal and bolt sizes, emblem

[67ChevyPickupMan]

I recently found on small window cab in a junkyard with a good back window and was wondering how to get it out without breaking/messing it up? I was also wondering what size the nuts and bolts are for the tow hooks? My last question is that there is a small badge/emblem on the dash by the ignition switch and I think it says air conditioning, and I was wondering if it's a onetime use part and if not, how do I remove it without breaking it as well?

Thanks to those who reply
