904 front pump,non lockup
Ok. I have 2 pumps. One I know is from a 67. One is from 68 and newer.
They have the same spline (26).
The splines shafts are the same dia on the outside but the 68 is larger dia inside.
On the back side of the pumps the shafts are different. 67 on the right.
What year is yours.
