Rear axle will probably be a AAM9.75 out of a 6.2 K1 truck. I still think the 10 bolt may be the ticket up front with some beef. The D60 would be great, but think for my purposes overkill and heavy.

I've moved away from the 8.1. It's just poorly supported.

I can't help at all on your transfer case question, but it is a good one and maybe someone will know. Your engine/trans idea is great and I think ideal for your goal. I believe you're correct in thinking a beef'd up 10 bolt up front will be ideal too. I believe off road design has chrome molly axle shafts available for them and I think those alone would be more than durable enough for a daily/trail rig. Looking forward to this build as I am a huge fan of your K5!
