Whats the major differences b/w the 67-70 and the 71-77 727's? I know pushbutton to 65, 66 was like a "transition year" (still course 19 spline input) and lock up was in 78. But I know there was changes b/w 70 and 71, I just cant remember what they were....lol. Thanks

The 3-prong shift lever (roostercomb) for '69-'70 is different than '71-on. The improved Belleville didn't arrive until '74. The INTERNET, the MISinformation superhighway
