Small Block 727 question

Hey guys,
I am in the process of collecting my parts to do my motor swap. I have a 74 Duster slant 6 with the a904 auto tran. I have a 318 that is going in the car. My question is I have someone that has a good 727 that is bolted to a 360 (motor stays unfortunately) that came out of a truck. Is there anything that would prevent that tranny from being used in the Duster? Shouldn't the cross members be in the same place. I am already going to need a new drive shaft so that isn't a concern right now.
