273/318 torque converter question

I should already know this, but just in case I forgot....

I know a 273 torque convertoer behind a 318 needs the snub/hub adaptor to center it correctly in the 318 crank....

My question and absent mindedness is this: Can I put a 69 318 torque converter in the 65 904 behind the 318? If so, no need for the funky spacer.... I have a good 904 converter that was in my Fury before I swapped to the 727....
