My car is 69 Dodge Polara convertible 383cui. I have checked the rockauto and they list 11x3 drums under 440cui engine trim. Its RAYBESTOS Part # 1938R, Front; 11" X 3" Brakes.

Will keep the fix as easy as possible, going with the no finned 11x3 drums. Driving mostly with the top down while cruisin, I´m easy on brakes. Will report the wheel fitment in few months, once have the parts imported to central Europe and snow is gone thanks everyone for help
