8.25 rear....1985 sure grip swap into a 1973 housing?

There is a thread on here by Halifax Hops. Check it out. Kim
That thread is a BEAST! I need some aspirin and my iPad has crashed 3 times. I'll grind through it tonight. My open carrier 1973 is a 2.71 and my 1985 sg is a 3.21. The. Offset looks similiar. Fingers crossed. Still open for advice but thanks for the help. This is my first in depth mopar build.
