heater core replacement '95 S10

I am about to attempt to replace heater core on '95 S10 Blazer 2wd. Am I nuts? I've been surfing AF and it seems it can be done although it is time consuming. I really dont care how long it takes, I just want to make sure I don't miss anything, leave anything to chance, or spend hours doing something I don't need to do. Thanks for any tips, instructions, warnings.

It's fairly straightforward, just time consuming like you said. There are some helpful tips in this thread...
