My 71 Cuda 383 4 speed, with 22.000 miles, bought with 17.000 miles in 1985 has a Bendix painted black. Built January 15. ALso my 71 Challenger 440 six pack has a Bendix in black, but more miles and just bought..so not certain if it was changed. But car has been on storage for several decades...tires are late seventies with thread in brand new condition. So probabli it has never been changed. Built march 71
