I recall the 67 BM Chevelle that I owned had an 11-18-66 build date for the rear and the car had an 06B of 1967 build date, so that would be a 7 month spread (4.56 with metallic drum brakes) and I am 100% certain it was original to the car as documented on the POP and plus other physical evidence. </div></div>

Two owners to date...Bob ordered it this way in '68. I'm just the caretaker since 74. It has never been apart........except for me busting the ring gear one late Saturday night up shifting into 2nd at 7400. (it was late and the neighbor was pissing me off about me adjusting the valves and carb with the headers
