I'm Cummins swapping a '74 Duster, thought I'd share the progress.

I just want to see how the coil overs do with all that extra weight and no torsion bars.

That said, I'm also curious why you're ditching t bars when you're running such a narrow motor.
I haven't test fit the G56 yet , but it's quite a big transmission so It might interfere with the hex keys of the torsion bars
