The truck build looks great, and should be interesting.
Please be careful. When you do things differently, people will criticize...
BUT, this Forum has many wise and experienced mechanics... the last time I followed one of these build threads, the person with the lifted truck (not as high as yours) replied that the truck had plenty of power, and rode nice, and did not address the gearing issues. Then shortly later the transmission completely melted down.
And the missing suspension nut should be addressed ASAP.
You are getting some good advice here. Just my opinion.
Good luck, and have fun!!!
