This used to be a huge topic on this site (and many others) but the main takeaway is that most of us don't live in your state and our rules and knowledge just won't apply. Most every state has a DMV website that'll get you started, and I would assume you kept paperwork showing where you got those parts from, so armed with that - you should be able to begin the process. I know when I did mine it sounded easy enough but it turned into a hassle as the state revised their program and how they wanted to apply titles for "assembled vehicles" the program was so new that the folks in the local offices had no idea what was supposed to happen and when! It was ... interesting... to say the least! LOL Good Luck and let us know how it goes.
