Two (or more?) Bent Pushrods

Looking at a Clevite engine parts book, the 64-67 273 pushrod is listed as being 7.490 oal(which would put the effective length at about .156” shorter).

The 68/69 273 is listed as using the same part number pushrod as the 68-88 318(w/o roller lifter).
7.500” oal, ball/ball.
