Hello, I have stashed in Muskegon Michigan complete left & right quarter panels for Regal / Grand National in a shed for about 20 years. Aside from dust, they are rust free and great condition. Are these even worth anything? I have a TH375 C3 Buick short transmission that was stout when replaced with 4L60. My car is an 81 Regal that started as a diesel and now holds my 350 Buick from high school LeSabre.
