Where do I even start

[03BlkZ]

Well my dad and I are going to start working his 70 C10 this week. My plans for the first day are to get it out of the shop where it has sat for almost 20 years. I want to get it out and give it a good bath and that will allow us easier access to clean up the shop a bit also to make more room. I would like to get it back in the shop and get it on some jack stands to start evaluation. From then we will decide how we want to proceed. Should be a good time working on this with dad but I a little overwhelmed on where to even begin. I kind of want to take it down to the frame but I think dad just wants to make it safe and reliable to drive again. It will have to be a compromise between us since we are splitting the cost of everything. What would you guys do? Definately the bed rails, headache rack and brush guard will be trashed. I'm excited to get started and learn alot from all the knowledge here. Thanks,
Brent
