Replacing my own windshield/rear glass 64 Val

I have a 64 Valiant 2 dr sedan rough driver. I need to replace the glass, gaskets and want to do it on the cheap. I'm pretty handy and am not intimidated by this kind of task, and I'd love to save the cash and spend the money on performance upgrades. Can any tell me what I have in store by doing it myself? Thx
