It sounds like you're at that point where things can really snowball on you. It's the question of 'Where do I stop'. You can take the cab off and do a better job of stripping the firewall and floor, but then you may as well blast the frame under the cab......then maybe pull the bed and do under there too. So you see You just have to ask yourself, how nice you want the truck, how much time do you realisticly have to do this build, and how big is your budget.

You can sand blast the firewall and floor without damaging the windshield as long as you mask it off and protect it well. I'm a big fan of blasting things down to bare metal so you can see just what is rusted, or full of mud and what isn't. That way when it is done, you know exactly what's underneath the paint, and that is isn't going to come back and bite you in the a$$.
