Slant 6 to 318 swap, 72 Duster, Using 75 D100

I'm not very knowledgeable in this area, but I have been led to believe the /6 and 318 a904 transmissions don't swap because of the bell housing and starter mounts. Maybe you plan to keep the trans and motors together but I don't think you specified that. Also, will the truck Trans bell housing fit under the car easily? Throttle linkage, torsion bar changes?

Please post your project, I'd be interest in following along.
