Will a 81 differential bolt into a 70? Thanks for any help!

In a word, no.

it will need to be slightly modified to fit I.E. Add brackets and drill or make holes bigger. You should do a search I think beejay did a batwing install and later the aluminum diff. he had a good how to on there but I believe his was a 78 vette though

Sure, here's a 81 in a 73.
