Crank shaft and rod questions.

anyone here know if a slant six 68 and up crank shaft will work with 67 rods and block. same size rod journals width and dia?
I'm getting a 67 /6 block freshened up, and I have a good newer (1970) 904 trans . I'm trying to leave my options open. Since I will need crank work done I would like to use a newer crank so I can use the good trans if I choose to. I just couldn't find journal specs for the width of rod for the 67 crank, where I could for the 68 - 76ish of 1.225 and 1.00 on the 80 up. Just wanting to make sure the 67 rods will fit a 68 -76 forged crank.
