I found a S-style no brand guitar that I really like but I want to upgrade the neck, hardware and pickups. Since this guitar cost me very little money to acquire, I figured it would be a good learning tool for doing all these upgrades. I have no previous experience with this and have been relaying on google and YouTube but I cannot find anything about what to look for when replacing a neck. I assume I cannot just get any guitar neck to fit.

Hello! This is going to be my first attempt at replacing hardware on my guitar. My question is how do I go about finding the specs I need for my guitar? I have the original neck that came with the guitar that I want to replace, so what dimensions or measurements do I need to look at? Any help will will be much appreciated. Thanks.
