BTTF1, BTTF2, BTTF2 Flying, BTTF3, BTTF3 Railroad, Train, and Flying Train models (manual's the simplest to install, but it's a huge download compared to the regular one.) The script is built upon the stripped script from the vice city mission builder. So far, I have the time travel script done, and am just troubleshooting the bugs and adding some new features if they come to my head. Me, K.I.T.T., Carlos EGL, and Keeper over at decided to start a new bttf conversion mod for GTAVC that adds hill valley, time travel, and deloreans.
