Olds/Pontiac 9.3 in an A-Body?

I am thinking the 9.3 is not going to be a good choice. Could I make it work? Yes. But toolmanmike was definitely correct in the amount of work/money required to do so mot being worth it. Thank you ALL for your insights and information. It is greatly appreciated.
It could be an expensive route. A guess a lot depends on the condition of said unit and then weigh the cost of modifying.

Honestly a great way to go is an all new Moser rear end. Google Moser and check out what they have to offer.
