You're the second UH-60 pilot with a early bronco that I've met. Not to sound too morbid but the first was a very good friend of mine shot down in the first gulf war. He was a good man. I was going to say kid, but we were all kid's back then. AH-64 pilot here, but I won't hold being a blackhawk pilot against you.
To get to your question. First thing to do after giving her a good bath will be to take an inventory and place everything into a good, restore or replace category. Prioritize this list from a safety first perspective. Brakes and driveline should top this list.
When you get to your items in the replace category you will then need to decide on if it's an item you wish to replace with a stock type replacement or an aftermarket upgrade. This is where the meaning of life type question resides for bronco owners. What do you want to do with it. Is this a weekend driver, an off road vehicle, etc. The reason we all love these things is that they can be built to do whatever we want to do with them. I live by the 70/30 rule. I think of where I'm going to be using this vehicle about 70% of the time and build accordingly. For me 20 years ago this was off road/light rock crawling so my bronco got built that way. Now I'm headed back to a mild manner street rig that only gets driven a couple days a week in the summer. Maybe for you this will be a daily driver. Each type of usage can help you make decisions on how you want to build out your rig. Just keep in mind that these things get in your soul and never leave. Do it right the first time, even if it means saving a bit for the right build.
