rebuild kit

Hi all. First time posting. Long time listener lol Im doing a stock rebuild on an 06 Dana 30 with 3.07 after wrecking. I couldnt reuse the old housing as the passenger axle tube and caster plates for CTRL arms were bent. I got a new housing on ebay but theres significant wall depth problem when...

I get to rebuild my NSG370 (yay!) and thought I’d rebuild the NV231 while it’s out. What kits do you like and what chains are you using? I’m hesitant to get any cheap crap.
