I would use the parts car as a working guide and not blow it apart as well. Only as needed to figure something out or use a part.
Your biggest hurdle will be the top.
I have my dad's 67 firebird which is basically a bare shell. No interior, not much under the hood... I'm going to have A LOT of time and money in researching and buying what's missing... it's not like I can buy a cheap 4 door version, or even a beat up one for any kind of affordable price, so I'll be catalog and pictures building it.
You're truck is amazing. You know what to do
