I spent the morning cleaning the frame rail area in preparation for installing the springs and rear end. I used lacquer thinner on a red rag and a lot of elbow grease and it worked great. It removed the years of dust and grime from the bottom. Interesting note: It looks like on 2nd Gen F-Bodies the factory had the rear axle snubbers installed on the body prior to being dipped in the primer bath at the assembbly plant. As you can see that is shiny metal under the area where the snubber was.
