Swapped out the original 7 1/4 for an 8 1/4 in our '70 Duster. Put the /6 - 904 combo back in for now; gonna upgrade to 318 - 904 in the near future.

Haven't shortened the driveshaft yet and only wanna have to do it once.

So, should the 'shaft length for the /6 - 904 - 8 1/4 be the same as 318 - 904 - 8 1/4?

Yes, the 904's are the same length and sit in the same spot so the driveshaft is the same. Once you shorten it for the 8.25 you'll be set.
