Can you explain a bit better, the lower and upper shift shaft are splined and should slide together. Don't understand the problem you are having.

Your engine should have the two piece metal cams which fit together. The lower cam is installed with the tangs lined up with the left front stud when the LU is in Fwd gear and then you mate the upper cam to it before installing the LU.

Due to the age of your engine and the quality of the previous manual I sent you, here is a link to a different 4 cylinder engine using the same cam setup. Scroll down to Fig, M12-63 for a good view of the lower cam and it's alignment to the left front stud.

Remember, the LU must be in Forward gear when you align the lower cam.
