3/4 Ton rear on K/10 Suburban?

['68OrangeSunshine]

I have a '67 K/10 Suburban. It's been sitting for some years. Six years ago I cannibalized the 12-Bolt Corp 3.73 Rear w/Auburn Posi and Moser axles off it to put on my '71 GMC Jimmy K/1500. The '67 rear fit on the '71, but I couldn't get the blown out [12-Bolt Corp 3.73 Eaton [factory] Posi Rear to fit on the Sub.
I'm wondering if I can fit a 14-Bolt 3.73 [non-posi] onto the Sub's springs?
Can I get 6 Lug axles made to fit a 14 Bolt? I saw a '74 14 Bolt in the PHX craigslist for not a lot of money.
