If you want a Dana 44 or Dana 60 front axle then I'd stick with the K5 frame.

The Sierra frame has independent front suspension (IFS), right?

So if you really want to use the Sierra frame AND a solid front axle you'd need to do a solid axle swap as well. If you want the IFS, then go the Sierra frame, i guess.

To me it's just easier to use the K5 frame and do new motor mounts for the LS.
