What bolts/fasteners do I need to install my bumpers on a 73 Charger?

I recently purchased a 1973 Charger that had just been sprayed with primer, and the guy hadn't put the front or rear bumpers or the doors back on yet. Looking at the car now that I've got it home, I don't have the fasteners or even know what size of bolt/stud/whatever to get to put them back on? Does anyone know where I can find this information on the net? I also think I need to replace the door hinges or at least get new pins and bushings for them, anyone know where I can get those as well? Thanks in advance for your help!!
