What rear end can I use?

[Rigo's 70 C10]

I am going to be converting my truck from leaf springs over to coils, maybe bags, what rear end can i use to replace the one that i have on there. I am planning on getting the trialing arm replacement from cpp 6372TRSAK 63-72 Complete Kit with Coolride or maybe with springs. I would like to get a good differential on my truck. I am also planning on swapping the engine out and replacing it with a 6.0 LQ4 and trans. Any and all comments will be greatly appreciated.

The easy way is to find a coil spring axle from a 67-72 truck. If you want 5 luge, then choose a 71-71 rear. Be sure to get the trailing arms and mounting hardware.

I was wanting to use an axle from a newer vehicle. Is that possible? Also, the kit that i am buying comes with everything.
Thanks,
