Hi and welcome check out Stot's thread for one idea of mounting diff.
Do a search for Saturn plans for the alterations to book spec for Mx5.
I used Mx5 diff and copied the front mount for the diff from one of the American sites, l also used the mx5 pedals on mine and mounted the diff 20mm further back than book spec which made the handbrake cables miss the frame, if you read some of the threads you'll see what I mean.
On mine I had the brackets made by Phil aka Talon Motor and used the Mx5 engine mounts.
Best of luck with your build.
Regards Mick.
