My understanding is the 64-67 years should interchange. So, in your example the 66 chevelle rear would be the way to go. Its because the upper control arms/mounts are different than the later years. This of course does not take into effect the total width of the diff or your drive shaft/yolk differences if any, in your example. There may not be a problem with that, but do your homework to make sure.

This site might explain some of the differences. http://www.oldsmobility.com/

The olds FAQ has some info has well. http://oldsjunction.classicoldsmobile.com/oldsfaq/
