Welcome to the forum mate. Love your attitude, starting from scratch, here to learn, avoiding the internet jerk off "experts" of social media. I am pretty sure you will find answers to all your needs over here. Just remember, Patrols have been around for decades, this forum here as well, so always take the time to use the forum search tools for topics of people having and/or fixing the same problems as you will eventually have. And if you don't find, don't feel embarrassed to put a new thread on it, people here have a lot experience on Patrols and automobiles in general, someone will most likely jump in to offer some advice.
Nicely put!
