The Ofna/Hobao Hyper 7/8/8.5 uses the 8 spiders as an option. I have the parts manual for the hyper 7.
Duster, it's listed as a Torsen but it's not. UE sells the Hyper 7 6 and 8 spider diffs. UE just added the shim kit, bearing, and diff outputs to the hyper diffs

. I never bought "UE 6 or 8 spider diffs". I just bought the UE 7.5 diff outputs and installed them on the Hyper diffs. Much cheaper (I get a military discount from UE too). Let em know if you need part number for your diffs (O-rings, 2.6mm screws etc.).
