68 Suburban 4x4 differentials

[Reno]

So I’m gathering parts for my 1968 Suburban 4x4 build.

I will be installing a Cummins and have availability to Dana 60 front & Dana 70 rear from a 1992 Dodge Cummins.

Or should I use a Dana 60 and 14 Bolt Floater from a Chevy donor truck?

I believe both fronts are bolts ins and the rears will probably need mounts moved.

Any advantages to either setup?

Thanks in advance....
