Early cuda leaf spring issues?

All stock. Car believe it or not has 6K on it one owner that died barley used it was last on the road ion 74. Trying to get it back to complete stock. Has a slant in it which I was surprised is rarer than the 273. Bare bones car except the radio and PS. Only real issue is it was never washed and has the typical body rot. Seriously don't think it was ever washed. Wife is in love with it so it will be hers when it is done. Kind of nice having a junker for some small parts. Definitely helps out but have to get it off the front lawn now!
