Hello all, project Jurassic jeep is getting some attention lately. I am removing the entire Interior and removing the fuel tank so I can cut the rusted floor and uniframe Frame rail sections. I will have to rebuild and re enforce the uniframe and leaf spring mounts. I plan to use some thick plates and tube steel to rebuild. My uniframe frame rails Are solid in a majority of the Cherokee, but in others they are paper thin. What gauge metal plates and tube steel is recommended for a frame and leaf spring mount repair?
