FLM Hybrids+1/8 diffs or UE 6 diffs w/aluminum bulks?

[Urgeoner]

okay thanks for the help George, again! Pics were nice!
Do the GA bulks have the diff cases machined in like the hybrids do? By looking at the pic you provided they don't. So when you say to go with the ofna or hot bodies diffs, UE output shafts, and the GA or FLM hybrids, did you mean just the FLM hybrids? Sorry if i'm confusing =)
Also, what size UE diff outputs?
And will this diff work with the Hybrid bulkhead:
