Outer Limits 4x4 Board

Hi, i'm wondering if i can fit GQ patrol Diff's on my MQ S.W.B. That is front and rear.. I noticed that gq's have what looks like mounting brackets for leaf springs on top of the diffs!! Springover?? What do you guys think am i getting too excited? has anyone tried this?

gq diffs are wider to start but any thing is possible.
Do a search, i'm sure it's been asked before.
