Hey Guys********* Just wondering if anyone know's of any frame supports for older stle mustangs . I am rebuilding a 67 now and im planning on getting some major HP out of my 427 cj . I am worried the stock frame will twist and figured i should beef it up. Im replacing the rear frame rails now so i have easy access .Has any one ever done any kind of extra frame support on there cars?Can i just weld on extra plates over the frame?Any info i could get would really help.Thanks Guys
