I used the 73 to 76 a-body spindle for disc brakes on my 64 Polara. I installed a 440 in my original 383 car. I narrowed a Dana 60 and fit 15x10 American TorqueThrust with 275/r60x15 T/As. My trans was a cross breed (64 push button with 65 slip yoke extension housing). The car now lives in Chicago. Picture files are too big to show
