68 - 72 A body 12 bolt from 442

[Lynn]

Have a chance to buy a 12 bolt for my 68 El Camino really cheap.
It is from a 442, coded SE 3.42 open rear (may be SF, may be 3.23... will need to confirm). Complete drum to drum.

Before I pull the trigger, can anyone confirm it is a bolt in for my 68 El Camino. Wanting to make sure the other divisions didn't have some weird difference.

I will be using it for towing from time to time, and would rather go through this 12 bolt rear and install, than go through the 10 bolt that is in it now.

Thanks for any guidance.
