Close to stock 70 Swinger

Hi guys. My project is getting close to road ready. I have small bolt 5x4 14" rim with 4.5" in between the beads. The car came with rotted 195 75 14. I'm keeping my steelies until I upgrade brakes and everything else, but thats a few years off. I want to give it a rake but I have a steep driveway. Any ideas on sizes and experiences?
