Small block 904 vs /6 904, any difference to drive shaft length?

Ol'forest said

Hi all, swapping from a slant 6 in my 75 duster to a 360, will run a 904. Want to know if there's any difference to drive shaft length in the two set ups? I heard somewhere that the slant 6 904's had a shorter tail shaft, is that right? I don't have a spare small block 904 to measure to check.

I just did this swap last weekend. It's a direct bolt-in along with the motor. When you change the rear-end is where you'll have the length issue. Dad already had the driveshaft cut when he changed to an 8 3/4 rear end years ago behind the /6. So when I swapped the 360/904 in place of the /6 and 904 the crossmember and driveshaft went right in place. I don't however know what linkage will cross over, as I'm using a floor mounted cable operated B&M shifter, Lokar(knockoff) throttle and kickdown cables, and none of the factory linkage.
