Slant six 904 torque converter questions

I have a 67 slant6 crank shaft for the small snout converter. I have 2 904s, one is a 67 ( I don't know how good this one is) and I have a pretty fresh 904 1970 with a larger dia. snout. My question is will the 67 converter swap into the 70 904 ( fit the input shaft splines and pump properly? ) Thanks for any info on this.
