the body back on the chassis and ready for the final blocking and paint
when narrowing a rear end you will need a narrowing/ truing bar and pucks. once the rear end is cut and re welded, if you cant spin the bar or the pucks by hand, it is warped. so you remove both pucks on the ends ( the bar is still being held and centered by the pucks that are in the carrier. so you slide the end pucks over to the bearing surface and see which way the housing is warped. then take a torch with a rose bud tip, and heat on the side that looks like it shrank close to the center section, i like to go just to the out side of the weld at the tube and center housing. heat up about half way around the tube to a dull red, it will expand past what it looks like it needs. then i tap the housing lightly with a hammer to relax the metal. let it cool and see how it moved, repeat the process until you can slide the pucks in easily by hand
