Slant six complete driveline swap

Hey all, I have a 73 duster that has a slant six in it but will be pulled out and getting replaced by a big block. I also have a 67 barracuda that has just been sitting, my buddies and I were wondering if the complete driveline from the duster (K member and suspension, engine, trans, driveshaft, springs, and rear end) would bolt up just fine? Any input would be great as I am having a hard time finding any info on slant six swaps as I am guessing they are not all that common hahaha.
