Old school rear look

Hey Guys, thanks for letting me join the forum. I have a 68 Dart GTS and I’m looking to go with deep dish Cragars in back and larger tires. I definitely want that big tires in back muscle car look. I’ll need to lift the rear to clear the wells, looking for some guidance as to how to go about this. I’m guessing I’ll need longer travel shocks. Rebuild the existing springs and add to them or just buy new ones. Thanks
