I am in the process of finishing a MPFI 383 to go back in my '90 K5. I was very "ticky" in removing nuts, bolts, fasteners, etc. I cleaned, and painted everything and kept them in labled Ziplock bags. The thing is that I still have some hardware that never made it to a bag so I don't know where it came from. (I'm sure I'll find out soon enough). Anyway, I had heard somewhere that on that show American Hotrod or whatever it is, that Boyd Coddington makes those guys actually TAG and label each individual nut and bolt with a description of where it came from on the vehicle. What do you guys do to keep all this crap organized?
