Engine changeout: front end removal?

[zac]

I know some of you guys have done this a dozen or more times. I'm just about ready to swap a new engine into my '70 K10 burb. I pulled the engine from a '72 several years ago, but I don't remember much about it, and it was complicated by severe rust. The grill, radiator and mounting panel have to come out obviously, can you take a couple minutes to give me some tips on which bolts need to come out, which ones I won't see, and which ones I shouldn't take out that I will think I should? What should I order now that almost always has to be replaced? This truck is pretty clean and I sprayed PB on all the likely-looking suspects, so I'm hoping it will go pretty easy. Stupid questions, I know. Thanks in advance.
